build: fix clang-cl builds, add CI job
- appveyor: add build-only job for clang-cl.

- cmake: `-pedantic-errors` enables `-Werror,-Wlanguage-extension-token`
  automatically, which makes `__int64` detection fail.
  Explictly disable this compiler warning for clang-cl to make the
  feature detection work and to accept `__int64` in the source code.

- cmake: disable `-Wlanguage-extension-token` warning for clang-cl
  to fix these when encountering `__int64`:
  ```
  lib/formdata.c(797,29): error : extension used [-Werror,-Wlanguage-extension-token]
  lib/warnless.c(117,33): error : extension used [-Werror,-Wlanguage-extension-token]
  lib/warnless.c(60,28): message : expanded from macro 'CURL_MASK_SCOFFT'
  lib/warnless.c(59,38): message : expanded from macro 'CURL_MASK_UCOFFT'
  include\curl/system.h(352,40): message : expanded from macro 'CURL_TYPEOF_CURL_OFF_T'
  ```

- make `__GNUC__` warning suppressions apply to `__clang__` too.
  Necessary for clang-cl, which defines the latter, but not the former.
  (Regular clang defines both.)

- examples: fix clang-cl compiler warning in `http2-upload.c`.
  ```
  docs\examples\http2-upload.c(56,5): error : no previous prototype for function 'my_gettimeofday' [-Werror,-Wmissing-prototypes]
  docs\examples\http2-upload.c(56,1): message : declare 'static' if the function is not intended to be used outside of this translation unit
  ```

- unit2604: add missing `#pragma GCC diagnostic pop`.
  Follow-up to e53523fef0 #14859

- unit1652: limit compiler warning suppression to GCC.
  They do not affect clang builds.
  Follow-up to 71cf0d1fca #14772

tests: speed up builds with single-binary test bundles
Add support for single-block binaries that contain all libtests and
unit tests respectively.

Enable with:
- autotools: `--enable-test-bundles`
- cmake: `-DCURL_TEST_BUNDLES=ON`

(They are compatible with `--enable-unity` and `-DCMAKE_UNITY_BUILD=ON`
options, for further speed-up.)

Makes libtests and unit tests build _fast_, needing little disk space
even in static mode. Similar to CMake unity mode, but with a custom
script, also supporting autotools builds.

The price is having to deal with symbols/macros colliding between
`lib*.c` and `unit*.c` sources. Maybe with naming conventions or other
solutions this can be improved gradually and reduce the need for manual
intervention by `mk-bundle.mk`. I've included a script that does the bulk
of detecting name collisions.

Also:
- CI: enable test bundles.
- CI: build tests in more jobs.
- lib2305: fix FILE handle leak.
- unit1661: fix memleak found by torture test by releasing the `bufref`
  structure in `unit_stop()` that was allocated in `unit_setup()`.
  ```
  test 1661...[bufref unit tests]
  Leak detected: memory still allocated: 13 bytes
   allocated by /home/runner/work/curl/curl/tests/unit/unit1661.c:70
   1661: torture FAILED: function number 1 in test.
  ```

cmake: separate target for examples, optimize CI, fix fallouts
- Move `docs/examples` builds under a separate target.

- Make `BUILD_EXAMPLES` default to `ON`. It means to generate the rules
  for `docs/examples` by default, but not build them. To build them,
  an explicit `make curl-examples` (or ninja, etc) command is necessary.
  This syncs behaviour with autotools, and also how both cmake and
  autotools are building tests.

- GHA: update cmake jobs to use the new way of building examples.

- GHA: move examples build step at the end of the job, after building
  and running tests. This allows to have build and test run results
  faster, and leave the seldom-changing examples build to the end.
  Building examples is the slowest build step with no practical way to
  make them fast.

- appveyor: enable building examples in two old-MSVC jobs.

- examples: fix examples to build cleanly with old MSVC versions.

- GHA/non-native: move example build log under a GHA foldable section.

- GHA/windows: move building examples into separate step for Linux cross
  jobs.

CI: move Azure jobs to GHA, fix fallouts, sshserver, runtests tweaks
CI:

- GHA/windows: enable OpenSSH server, SysInternals `handle`, `impacket`.
  Skip `impacket` on MSYS2 due to install failure.
  Skip OpenSSH server for old/standalone mingw-w64 (building curl
  without SSH there.)
- GHA/windows: make test tool installs a separate step.
- GHA/cygwin: enable OpenSSH server.
  Skip `impacket`: it's compiling for 7 minutes then breaks.
  Skip `stunnel` due to sluggish test run performance.
  (This update is unrelated to Azure jobs.)
- GHA/linux: migrate Linux jobs from Azure CI.
- GHA/linux: migrate scanbuild job from Azure CI.
- GHA/linux: enable libssh2 in a job. Also enable valgrind.
- CI/windows: enable SSPI in two jobs.
- CI/windows: disable zlib in one more job.
- CI/windows: improve `if` condition checking GnuTLS.
- CI/windows: ignore SFTP/SCP tests as necessary.
  - universally ignore SCP tests, they fail everywhere.
  - ignore test 612.
  - ignore test 613 616 618 with MSYS2 mingw-w64.
  - ignore test 614 with libssh.
  - ignore all SFTP with MSYS2 native.
  - ignore all SFTP with vcpkg with `libssh2[core,zlib]`.
  - ignore a couple of SFTP tests with MSYS2 mingw-w64.
  (This matches settings on Azure CI.)
- GHA/windows: ignore failing 1451 'Basic SMB request' test for
  old mingw-w64 7.3.0 (but not for 9.5.0!):
  ```

- CI/Azure: delete, now moved to GHA.

sshserver:

- sshserver: fix permissions for SSH host key on Windows, allowing sshd
  to launch.
- sshserver: fix initializing config paths with Cygwin/MSYS2 sshd.
- sshserver: fix initializing config paths in parallel builds.
- sshserver: delete redundant `DenyUsers`. This also opens the way
  to allow multiple usernames.
- sshserver: fix `AllowUsers` for GHA/windows, by allowing the
  domainless username again.
  Follow-up to 3ee7c676ec #5721
- sshserver: fix `Deprecated option` warnings in `sshd_config`:
  ```
  D:/a/curl/curl/bld/tests/log/2/server/curl_sshd_config line 7: Deprecated option AuthorizedKeysFile2
  D:/a/curl/curl/bld/tests/log/2/server/curl_sshd_config line 25: Deprecated option KeyRegenerationInterval

  D:/a/curl/curl/bld/tests/log/2/server/curl_sshd_config line 41: Deprecated option UseLogin
  ```
- sshserver: fix `Deprecated option` warnings in `ssh_config` with
  Cygwin/MSYS2.
- sshserver: fix dumping config files due to the filenames missing their
  full paths.
- sshserver: add workaround to make `logmsg` messages visible.
  Before this patch they only went to a file and never shown.

runtests:

- runtests: log details when these Windows commands are called:
  `handle`, `taskkill`, `tasklist`.
- runtests: add documentation links to Windows tools:
  `handle`, `taskkill`, `tasklist`, `icacls`.
- runtests: add `-t` (kill whole tree) option to `taskkill` in
  `servers.pm`, syncing it with the other `taskkill` call.
  Follow-up to bc72a78a11 #14488
- runtests: show warning if Sysinternals `handle` tool is missing.
- runtests: drop Windows XP Home compatibility `tskill` call.
  The call was made on all Windows versions. It's possibly overkill to
  do this, because XP Home is probably rarely used for running curl
  tests these days. In case it's needed, it'd be better to put it under
  an explicit option.
- runtests: show Perl version and path.

Fix/silence fallouts:

- unit2603: fix building with disabled HTTP support.
- unit2604: silence `-Woverlength-strings` warnings in C89 mode.
- test437, test1614: fix to pass with no-IPv6 builds.

GHA/non-native: improve, migrate x86_64 FreeBSD with tests from Cirrus CI
- run tests via `make test-ci` instead of `make check` with autotools.
- add `x86_64` job for FreeBSD, with tests.
  It matches the existing Cirrus CI job, with these differences:
  - finishes 3x faster (thanks to parallel tests enabled).
  - librtmp is not enabled because it's slated for removal by FreeBSD.
    (already past the removal deadline, thought the package still
    installs.)
  - DICT and TELNET servers fail to start. Couldn't figure out why.
    It means skipping test 1450 and 1452.
  - it runs more tests, e.g. websockets and ip6-localhost.
  - no `pkg update -f`.
  - it misses the `CRYPTOGRAPHY_DONT_BUILD_RUST=1`, `pkg delete curl`,
    `chmod 777`, `sudo -u nobody` and `sysctl net.inet.tcp.blackhole`
    tricks. The latter is the default in these runners, the others did
    not affect results.
- set `-j0` for tests in the NetBSD job. Flaky otherwise.

build: untangle CURLDEBUG and DEBUGBUILD macros
`CURLDEBUG` is meant to enable memory tracking, but in a bunch of cases,
it was protecting debug features that were supposed to be guarded with
`DEBUGBUILD`.

Replace these uses with `DEBUGBUILD`.

This leaves `CURLDEBUG` uses solely for its intended  purpose: to enable
the memory tracking debug feature.

Also:
- autotools: rely on `DEBUGBUILD` to enable `checksrc`.
  Instead of `CURLDEBUG`, which worked in most cases because debug
  builds enable `CURLDEBUG` by default, but it's not accurate.
- include `lib/easyif.h` instead of keeping a copy of a declaration.
- add CI test jobs for the build issues discovered.

build: untangle UNITTESTS and DEBUGBUILD macros
- fix `DEBUGBUILD` guards that should be `UNITTESTS`, in libcurl code
  used by unit tests.
- fix guards for libcurl functions used in unit tests only.
- sync `UNITTEST` attribute between declarations and definitions.
- drop `DEBUGBUILD` guard from test `unit2600`.
- fix guards for libcurl HSTS code used by both a unit test (`unit1660`)
  and `test0446`.
- update an existing AppVeyor CI job to test the issues fixed.

This fixes building tests with `CURLDEBUG` enabled but `DEBUGBUILD`
disabled. This can happen when building tests with CMake with
`ENABLE_DEBUG=ON` in Release config, or with `ENABLE_CURLDEBUG=ON`
and _without_ `ENABLE_DEBUG=ON`. Possibly also with autotools
when using `--enable-curldebug` without `--enable-debug`.

CI: tidy up skipping tests build/run in Windows jobs
Simplify controlling whether to build and/run tests in a CI job.

Apply the TFLAGS='skipall' (do not build nor run tests) or
'skiprun' (build, but do not run) method already used with old-mingw-w64
and msvc jobs to existing Windows jobs in GHA and AppVeyor.

Also:
- add Cygwin/cmake test build and run steps while here.
- replace `DISABLED_TESTS` with `TFLAGS` in AppVeyor.

cmake: ENABLE_DEBUG=ON to always set -DDEBUGBUILD
Before this patch `ENABLE_DEBUG=ON` always enabled the TrackMemory
(aka `ENABLE_CURLDEBUG=ON`) feature, but required the `Debug` CMake
configration to actually enable curl debug features
(aka `-DDEBUGBUILD`).

Curl debug features do not require compiling with C debug options. This
also made enabling debug features unintuitive and complicated to use.
Due to other issues (subject to PR #13694) it also caused an error in
default (and `Release`/`MinSizeRel`/`RelWithDebInfo`) configs, when
building the `testdeps` target:
```
ld: CMakeFiles/unit1395.dir/unit1395.c.o: in function `test':
unit1395.c:(.text+0x1a0): undefined reference to `dedotdotify'
```
Ref: https://github.com/curl/curl/actions/runs/9037287098/job/24835990826#step:3:2483

Fix it by always defining `DEBUGBUILD` when setting `ENABLE_DEBUG=ON`.
Decoupling this option from the selected CMake configuration.

Note that after this patch `ENABLE_DEBUG=ON` unconditionally enables
curl debug features. These features are insecure and unsuited for
production. Make sure to omit this option when building for production
in default, `Release` (and other not-`Debug`) modes.

Also delete a workaround no longer necessary in GHA CI jobs.

GHA: add three old (gcc 6, 7, 9) mingw-w64 jobs
Re-implement old mingw-w64 jobs in GHA. This allows to use the latest
Windows runners, replacing Windows Server 2012 R2 (gcc 6) and Windows
Server 2016 (gcc 7, 9) with Windows Server 2022.

GHA runners are also significantly faster, and allow running tests in
parallel (`-j14`). It also offloads 3 more long-running jobs from
AppVeyor CI.

These jobs download (then cache) the mingw-w64 packages from their
original location, which allows flexibility in choosing which versions
and flavours (win32/POSIX, SEH/DWARF, 64/32-bit) we want to test in CI.
The new jobs use these distros:
- https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/ (for gcc 7, same as on AppVeyor)
- https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/mingw-builds/ (for gcc 6, same as on AppVeyor)
- https://winlibs.com/ (for gcc 9)

I matched existing AppVeyor job configs, with these differences:
- gcc 6.4.0 instead of 6.3.0.
  (same distro as on AppVeyor, but the latest bugfix release)
- gcc 9.5.0 instead of 9.1.0 and a different (but compatible) binary distro.
  (in AppVeyor this relies on an old MSYS2 pre-installed on the runner)
- using win32 builds instead of posix for gcc 6.4.0 and 7.3.0.
- websockets enabled.
- always build examples.
- always build tests (this wasn't done for 6.4.0 with AppVeyor CI).

I did not replicate existing test exclusions, and oddly enough the few
failures (so far) were different from MSYS2 jobs and also from their
AppVeyor CI counterparts.

Also:
- delete redundant (default) `-u` option from `cygpath` calls.
- allow matrix options to override default ones in CMake.
- detect and use Windows-supplied curl for `TFLAGS` `-ac` option.
  (it's available in modern runners.)
- delete the 3 AppVeyor CI jobs now replicated in GHA.
- appveyor: prefer `SYSTEMROOT` over `WINDIR`.
- tidy-up quotes.

GHA: add MSYS, mingw-w64, Cygwin jobs
- re-implement autotools MSYS and Cygwin AppVeyor jobs in GHA.
  Now build with SSL and PSL to improve test coverage.
- re-implement MSYS2 mingw-w64 gcc 13 AppVeyor job in GHA.
  `CMake, mingw-w64, gcc 13, Debug, x64, Schannel, Static, Unicode`
- add new cmake Cygwin job (build-only).
- enable `-j14` parallelism when running tests.
- delete the 5 migrated jobs from AppVeyor CI.
- add 2 build-only mingw-w64 builds, gcc Release and clang OpenSSL.
- also enable brotli, libssh2, nghttp2 for more test coverage.

These jobs offer better performance, more flexibility and
parallelization compared to the AppVeyor ones they replace. It also
offloads AppVeyor, allowing to iterate faster. They also appear more
reliable than e.g. Azure Windows jobs, where runners are prone to fail
[1].

docs: introduce "curldown" for libcurl man page format
curldown is this new file format for libcurl man pages. It is markdown
inspired with differences:

- Each file has a set of leading headers with meta-data
- Supports a small subset of markdown
- Uses .md file extensions for editors/IDE/GitHub to treat them nicely
- Generates man pages very similar to the previous ones
- Generates man pages that still convert nicely to HTML on the website
- Detects and highlights mentions of curl symbols automatically (when
  their man page section is specified)

tools:

- cd2nroff: converts from curldown to nroff man page
- nroff2cd: convert an (old) nroff man page to curldown
- cdall: convert many nroff pages to curldown versions
- cd2cd: verifies and updates a curldown to latest curldown

This setup generates .3 versions of all the curldown versions at build time.

CI:

Since the documentation is now technically markdown in the eyes of many
things, the CI runs many more tests and checks on this documentation,
including proselint, link checkers and tests that make sure we capitalize the
first letter after a period...

appveyor: replace PowerShell with bash + parallel autotools
PowerShell works (after a steep development curve), but one property of
it stuck and kept causing unresolvable usability issues: With
`$ErrorActionPreference=Stop`, it does abort on failures, but shows only
the first line of the error message. In `Continue` mode, it shows the
full error message, but doesn't stop on all errors. Another issue is
PowerShell considering any stderr output as if the command failed (this
has been improved in 7.2 (2021-Nov), but fixed versions aren't running
in CI and will not be for a long time in all test images.)

Thus, we're going with bash.

Also:
- use `-j2` with autotools tests, making them finish 5-15 minutes per
  job faster.
- omit `POSIX_PATH_PREFIX`.
- use `WINDIR`.

cmake: pre-fill rest of detection values for Windows
The goal of this patch is to avoid unnecessary feature detection work
when doing Windows builds with CMake. Do this by pre-filling well-known
detection results for Windows and specifically for mingw-w64 and MSVC
compilers. Also limit feature checks to platforms where the results are
actually used. Drop a few redundant ones. And some tidying up.

- pre-fill remaining detection values in Windows CMake builds.

  Based on actual detection results observed in CI runs, preceding
  similar work over libssh2 and matching up values with
  `lib/config-win32.h`.

  This brings down CMake configuration time from 58 to 14 seconds on the
  same local machine.

  On AppVeyor CI this translates to:
  - 128 seconds -> 50 seconds VS2022 MSVC with OpenSSL (per CMake job):
    https://ci.appveyor.com/project/curlorg/curl/builds/48208419/job/4gw66ecrjpy7necb#L296
    https://ci.appveyor.com/project/curlorg/curl/builds/48217440/job/8m4fwrr2fe249uo8#L186
  - 62 seconds -> 16 seconds VS2017 MINGW (per CMake job):
    https://ci.appveyor.com/project/curlorg/curl/builds/48208419/job/s1y8q5ivlcs7ub29?fullLog=true#L290
    https://ci.appveyor.com/project/curlorg/curl/builds/48217440/job/pchpxyjsyc9kl13a?fullLog=true#L194

  The formula is about 1-3 seconds delay for each detection. Almost all
  of these trigger a full compile-link cycle behind the scenes, slow
  even today, both cross and native, mingw-w64 and apparently MSVC too.
  Enabling .map files or other custom build features slows it down
  further. (Similar is expected for autotools configure.)

- stop detecting `idn2.h` if idn2 was deselected.
  autotools does this.

- stop detecting `idn2.h` if idn2 was not found.
  This deviates from autotools. Source code requires both header and
  lib, so this is still correct, but faster.

- limit `ADDRESS_FAMILY` detection to Windows.

- normalize `HAVE_WIN32_WINNT` value to lowercase `0x0a12` format.

- pre-fill `HAVE_WIN32_WINNT`-dependent detection results.
  Saving 4 (slow) feature-detections in most builds: `getaddrinfo`,
  `freeaddrinfo`, `inet_ntop`, `inet_pton`

- fix pre-filled `HAVE_SYS_TIME_H`, `HAVE_SYS_PARAM_H`,
  `HAVE_GETTIMEOFDAY` for mingw-w64.
  Luckily this do not change build results, as `WIN32` took
  priority over `HAVE_GETTIMEOFDAY` with the current source
  code.

- limit `HAVE_CLOCK_GETTIME_MONOTONIC_RAW` and
  `HAVE_CLOCK_GETTIME_MONOTONIC` detections to non-Windows.
  We're not using these in the source code for Windows.

- reduce compiler warning noise in CMake internal logs:
  - fix to include `winsock2.h` before `windows.h`.
    Apply it to autotools test snippets too.
  - delete previous `-D_WINSOCKAPI_=` hack that aimed to fix the above.
  - cleanup `CMake/CurlTests.c` to emit less warnings.

- delete redundant `HAVE_MACRO_SIGSETJMP` feature check.
  It was the same check as `HAVE_SIGSETJMP`.

- delete 'experimental' marking from `CURL_USE_OPENSSL`.

- show CMake version via `CMakeLists.txt`.
  Credit to the `zlib-ng` project for the idea:
  61e181c8ae/CMakeLists.txt (L7)

- make `CMake/CurlTests.c` pass `checksrc`.

- `CMake/WindowsCache.cmake` tidy-ups.

- replace `WIN32` guard with `_WIN32` in `CMake/CurlTests.c`.

`lib/curl_multibyte.c` (as even noted in a comment there.) In unity
builds all headers apply to all sources, including `curl_multibyte.c`.
This probably resulted in an infinite loop on startup.

Exclude this source from unity compilation with TrackMemory enabled,
in both libcurl and curl tool. Enable unity mode for a debug Unicode
CI job to keep it tested. Also delete the earlier workaround that
fully disabled unity for affected builds.

appveyor: rewrite batch in PowerShell + CI improvements
1. Rewrite in PowerShell:

- rewrite MS-DOS batch build script in PowerShell.
- move some bash operations into native PowerShell.
- fixups for PowerShell insisting on failure when a command outputs
  something to stderr.
- fix to actually run `curl -V` after every build.
  (and exclude ARM64 builds.)
- also say why we skipped `curl -V` if we had to skip.
- fix CMake warnings about unused configuration variables, by adapting
  these dynamically for build cases.
- dedupe OpenSSL path into a variable.
- disable `test1451` failing with a warning anyway due to missing python
  impacket. (after trying and failing to install impacket)
  PowerShell promotes these warnings to errors by PowerShell. We can also
  suppress they wholesale if they start causing issues in the future,
  like we already to with `autoreconf` and `./configure`.

PowerShell is better than MS-DOS batches, so the hope is this makes it
easier to extend and maintain the AppVeyor build logic. POSIX/bash isn't
supported inline by AppVeyor on Windows build machines, but we are okay
to keep it in an external script, so it's also an option.

2. CI improvements:

- enable tests for a "unity" build job.
- speed-up CI initialization by using shallow clones of the curl repo.
- speed-up CMake MSVC jobs with `TrackFileAccess=false`.
- enable parallelism in `VisualStudioSolution` builds.
- display CMake version before builds.
- always show the CPU in job names.
- tell which jobs are build-only in job names.
- move `TESTING:` value next to `DISABLED_TESTS:` in two jobs.
- add `config.log` (autotools) to dumped logs (need to enable manually).

3. Style:

- use single-quotes in YAML like we do in other CI YAML files.
  It also allows to drop quoting characters and lighter to write/read.
  (keep double quotes for PowerShell strings needing expansion.)

appveyor: minor improvements
- run `curl -V` after builds to see if they run and with what features.
  Except for one job where a CRT DLL is missing. And ARM64 which should
  fail, but is silently not launched instead.

- copy libcurl DLL next to curl tool and tests binaries in shared mode.
  This makes it possible to run the tests. (We don't run tests after
  these builds yet.)

- list the DLLs and EXEs present after the builds.

- add `DEBUG` variable for CMake builds to allow disabling it, for
  testing non-debug builds. (currently enabled for all)

- add commented lines that dump CMake configuration logs for debugging
  build/auto-detection issues.

- add gcc version to jobs where missing.

- switch a job to the native MSYS2 mingw-w64 toolchain. This adds gcc 9
  to the build mix.

- make `SHARED=OFF` and `OPENSSL=OFF` defaults global.

- delete a duplicate backslash.

cmake: detect TLS-SRP in OpenSSL/wolfSSL/GnuTLS
With new option `CURL_DISABLE_SRP=ON` to force-disable it.
To match existing option and detection logic in autotools.

Also:
- fix detecting GnuTLS.
  We assume `nettle` as a GnuTLS dependency.
- add CMake GnuTLS CI job.
- bump AppVeyor CMake OpenSSL MSVC job to OpenSSL 1.1.1 (from 1.0.2)
  TLS-SRP fails to detect with 1.0.2 due to an OpenSSL header bug.
- fix compiler warning when building with GnuTLS and disabled TLS-SRP.
- fix comment typos, whitespace.

mingw: delete support for legacy mingw.org toolchain
Drop support for "old" / "legacy" / "classic" / "v1" / "mingw32" MinGW:
  https://en.wikipedia.org/wiki/MinGW, https://osdn.net/projects/mingw/
Its homepage used to be http://mingw.org/ [no HTTPS], and broken now.
It supported the x86 CPU only and used a old Windows API header and
implib set, often causing issues. It also misses most modern Windows
features, offering old versions of both binutils and gcc (no llvm/clang
support). It was last updated 2 years ago.

curl now relies on toolchains based on the mingw-w64 project:
https://www.mingw-w64.org/  https://sourceforge.net/projects/mingw-w64/
https://www.msys2.org/  https://github.com/msys2/msys2

223f601c04 test1056: disable on Windows
This test relies on the IPv6 scope field being ignored when connecting to
ipv6-localhost (i.e. [::1%259999] is treated as [::1]). Maybe this is a bit
dodgy, but it works on all our test platforms except Windows. This
test was disabled manually on all Windows CI builds already, so instead
add an incompatible feature and precheck so it's skipped on Windows
everywhere automatically.

cmake: add support for "unity" builds
Aka "jumbo" or "amalgamation" builds. It means to compile all sources
per target as a single C source. This is experimental.

You can enable it by passing `-DCMAKE_UNITY_BUILD=ON` to cmake.
It requires CMake 3.16 or newer.

It makes builds (much) faster, allows for better optimizations and tends
to promote less ambiguous code.

Also add a new AppVeyor CI job and convert an existing one to use
"unity" mode (one MSVC, one MinGW), and enable it for one macOS CI job.

Fix related issues:
- add missing include guard to `easy_lock.h`.
- rename static variables and functions (and a macro) with names reused
  across sources, or shadowed by local variables.
- add an `#undef` after use.
- add a missing `#undef` before use.
- move internal definitions from `ftp.h` to `ftp.c`.
- `curl_memory.h` fixes to make it work when included repeatedly.
- stop building/linking curlx bits twice for a static-mode curl tool.
  These caused doubly defined symbols in unity builds.
- silence missing extern declarations compiler warning for ` _CRT_glob`.
- fix extern declarations for `tool_freq` and `tool_isVistaOrGreater`.
- fix colliding static symbols in debug mode: `debugtime()` and
  `statename`.
- rename `ssl_backend_data` structure to unique names for each
  TLS-backend, along with the `ssl_connect_data` struct member
  referencing them. This required adding casts for each access.
- add workaround for missing `[P]UNICODE_STRING` types in certain Windows
  builds when compiling `lib/ldap.c`. To support "unity" builds, we had
  to enable `SCHANNEL_USE_BLACKLISTS` for Schannel (a Windows
  `schannel.h` option) _globally_. This caused an indirect inclusion of
  Windows `schannel.h` from `ldap.c` via `winldap.h` to have it enabled
  as well. This requires `[P]UNICODE_STRING` types, which is apperantly
  not defined automatically (as seen with both MSVS and mingw-w64).
  This patch includes `<subauth.h>` to fix it.

- tweak unity builds to compile `lib/memdebug.c` separately in memory
  trace builds to avoid PP confusion.
- force-disable unity for test programs.
- do not compile and link libcurl sources to libtests _twice_ when libcurl
  is built in static mode.

KNOWN ISSUES:
- running tests with unity builds may fail in cases.
- some build configurations/env may not compile in unity mode. E.g.:
