cmake: rework options to enable curl and libcurl docs
Rework CMake options for building/using curl tool and libcurl manuals.

- rename `ENABLE_MANUAL` to `ENABLE_CURL_MANUAL`, meaning:
  to build man page and built-in manual for curl tool.

- rename `BUILD_DOCS` to `BUILD_LIBCURL_DOCS`, meaning:
  to build man pages for libcurl.

- `BUILD_LIBCURL_DOCS` now works without having to enable
  `ENABLE_CURL_MANUAL` too.

- drop support for existing CMake-level `USE_MANUAL` option to avoid
  confusion. (It used to work with the effect of current
  `ENABLE_CURL_MANUAL`, but only by accident.)

cmake: speed up curldown processing, enable by default
- cmake: enable `BUILD_DOCS` by default (this controls converting and
  installing `.3` files from `.md` sources)

- cmake: speed up generating `.3` files by using a single command per
  directory, instead of a single command per file. This reduces external
  commands by about a thousand. (There remains some CMake logic kicking
  in resulting in 500 -one per file- external `-E touch_nocreate` calls.)

- cd2nroff: add ability to process multiple input files.

- cd2nroff: add `-k` option to use the source filename to form the
  output filename. (instead of the default in-file `Title:` line.)

cmake: fix ENABLE_MANUAL option
Fix the `ENABLE_MANUAL` option. Set it to default to `OFF`.

Before this patch `ENABLE_MANUAL=ON` was a no-op, even though it was the
option designed to enable building and using the built-in curl manual.
(`USE_MANUAL=ON` option worked for this instead, by accident).

build: remove redundant CURL_PULL_* settings
These macros were not propagated to the source code from CMake.

autotools set only one of them (`CURL_PULL_SYS_POLL_H`), initially to
address an AIX issue [1]. This later broke when introducing `system.h`
[2] without the logic it enabled. A subsequent fix [3] re-added the
logic, and also enabled it for AIX before its use, directly in
`system.h`.

system.h: sync mingw CURL_TYPEOF_CURL_SOCKLEN_T with other compilers
Align mingw with the other Windows compilers and use the `int` type for
`CURL_TYPEOF_CURL_SOCKLEN_T` (and thus for `curl_socklent_t`). This
makes it unnecessary to make a mingw-specific trick and pull all Windows
headers early just for this type definition. This type is specific to
Windows, not to the compiler. mingw-w64's Windows header maps it to
`int` too.

With this we also delete all remaining uses of `CURL_PULL_WS2TCPIP_H`.

[ The official solution is to use `socklen_t` for all Windows compilers.
In this case we may want to update `curl/curl.h` to pull in Windows
headers before `system.h`. ]

- move Watt-32 and lwIP socket support to `setup-win32.h` from
  `config-win32.h`. It opens up using these with all build tools. Also

cmake: delete obsolete TODOs more [ci skip]
- manual completed: 898b012a9b #1288
- soname completed: 5de6848f10 #10023
- bunch of others that are completed
- `NTLM_WB_ENABLED` is implemented in a basic form, and now also
  scheduled for removal, so a TODO at this point isn't useful.

And this 'to-check' item:

Q: "The cmake build selected to run gcc with -fPIC on my box while the
   plain configure script did not."

A: With CMake, since 2ebc74c36a #11546
   and fc9bfb1452 #11627, we explicitly
   enable PIC for libcurl shared lib. Or when building libcurl for
   shared and static lib in a single pass. We do this by default for
   Windows or when enabled by the user via `SHARE_LIB_OBJECT`.
   Otherwise we don't touch this setting. Meaning the default set by
   CMake (if any) or the toolchain is used. On Debian Bookworm, this
   means that PIC is disabled for static libs by default. Some platforms
   (like macOS), has PIC enabled by default.
   autotools supports the double-pass mode only, and in that case
   CMake seems to match PIC behaviour now (as tested on Linux with gcc.)

cmake: delete obsolete TODO items [ci skip]
There is always room for improvement, but CMake is up to par now with
autotools, so there is no longer a good reason to keep around these
inline TODO items.

Answering one of questions:

Q: "The gcc command line use neither -g nor any -O options. As a
   developer, I also treasure our configure scripts's --enable-debug
   option that sets a long range of "picky" compiler options."

A: CMake offers the `CMAKE_BUILD_TYPE` variable to control debug info
   and optimization level. E.g.:
   - `Release`    = `-O3` + no debug info
   - `MinSizeRel` = `-Os` + no debug info
   - `Debug`      = `-O0` + debug info

   https://cmake.org/cmake/help/latest/manual/cmake-buildsystem.7.html#default-and-custom-configurations

   For picky warnings we have the `PICKY_COMPILER` options, enabled by

0f3f384343 build: fix Windows ADDRESS_FAMILY detection
- Include winsock2.h for Windows ADDRESS_FAMILY detection.

Prior to this change cmake detection didn't work because it included
ws2def.h by itself, which is missing needed types from winsock2.h.

Prior to this change autotools detection didn't work because it did not
include any Windows header.

In both cases libcurl would fall back on unsigned short as the address
family type, which is the same as ADDRESS_FAMILY.

and `HAVE_MACH_ABSOLUTE_TIME` do require this C99 header. It means that

cmake: speed up threads setup for Windows
Win32 threads are always available. We enabled them unconditionally
(with `ENABLE_THREADED_RESOLVER`). CMake built-in thread detection
logic has this condition hard-coded for Windows as well (since at least
2007).

Instead of doing all the work of detecting pthread combinations on
Windows, then discarding those results, skip these efforts and assume
built-in thread support when building for Windows.

This saves 1-3 slow CMake configuration steps.

cmake: speed up zstd detection
Before this patch we detected the presence of a specific zstd API to
see if we can use the library. zstd published that API in its first
stable release: v1.0.0 (2016-08-31).

Replace that method by detecting the zstd library version instead and
accepting if it's v1.0.0 or newer. Also display this detected version
and display a warning if the zstd found is unfit for curl.

We use the same version detection method as zstd itself, via its public
C header.

This deviates from autotools which keeps using the slow method of
looking for the API by building a test program. The outcome is the same
as long as zstd keeps offering this API.

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`.

cmake: replace check_library_exists_concat()
The idea of `check_library_exists_concat()` is that it detects an
optional component and adds it to the list of libs that we also use in
subsequent component checks. This caused problems when detecting
components with unnecessary dependencies that were not yet built.

CMake offers the `CMAKE_REQUIRED_LIBRARIES` variable to set libs used
for component checks, which we already use in most cases. That left 4
uses of `check_library_exists_concat()`. Only one of these actually
needed the 'concat' feature (ldap/lber).

Delete this function and replace it with standard
`check_library_exists()` and manual management of our `CURL_LIBS`
list we use when linking build targets. And special logic to handle the
ldap/lber case.

(We have a similar function for headers: `check_include_file_concat()`.
It works, but problematic for performance reasons and because it hides
the actual headers required in `check_symbol_exists()` calls.)

  CMake-specific `CURL_USE_OPENLDAP` configuration.

- cmake: define `LDAP_DEPRECATED=1` for OpenLDAP.
  Like autotools does. This fixes a long list of these warnings:
  ```
  /usr/local/opt/openldap/include/ldap.h:1049:5: warning: 'LDAP_DEPRECATED' is not defined, evaluates to 0 [-Wundef]
  ```

- cmake: delete LDAP TODO comment no longer relevant.

Also:

- autotools: replace domain name `dummy` with `0.0.0.0` in LDAP feature
  detection functions.

cmake: fix unity with Windows Unicode + TrackMemory
Found the root cause of the startup crash in unity builds with Unicode
and TrackMemory enabled at the same time.

We must make sure that the `memdebug.h` header doesn't apply to
`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.

cmake: disable unity mode with Windows Unicode + TrackMemory
"TrackMemory" is `ENABLE_DEBUG=ON` (aka `ENABLE_CURLDEBUG=ON`,
aka `-DCURLDEBUG`).

There is an issue with memory tracking and Unicode when built in "unity"
mode, which results in the curl tool crashing right on startup, even
without any command-line option. Interestingly this doesn't happen under
WINE (at least on the system I tested this on), but consistenly happens
on real Windows machines. Crash is 0xC0000374 heap corruption. Both
shared and static curl executables are affected.

This limitation probably won't hit too many people, but it remains
a TODO to find and fix the root cause and drop this workaround.

cmake: fix HAVE_LDAP_SSL, HAVE_LDAP_URL_PARSE on non-Windows
- set `HAVE_LDAP_URL_PARSE` if `ldap_url_parse` function exists.
  Before this patch we set it based it on the presence of `stricmp`,
  which correctly enabled it on e.g. Windows, but was inaccurate for
  other platforms.

- always set `HAVE_LDAP_SSL` if an LDAP backend is detected and
  LDAPS is not explicitly disabled. This mimics autotools behaviour.
  Previously we set it only for Windows LDAP. After this fix, LDAPS is
  correctly enabled in default macOS builds.

- enable LDAP[S] for a CMake macOS CI job. Target OS X 10.9 (Mavericks)
  to avoid deprecation warnings for LDAP API.

- always detect `HAVE_LDAP_SSL_H`, even with LDAPS explicitly disabled.
  This doesn't make much sense, but let's do it to sync behaviour with
  autotools.

- fix benign typo in variable name.

cmake: validate CURL_DEFAULT_SSL_BACKEND config value
Before this patch CMake builds accepted any value and it was used at
runtime as-is. This patch make sure that the selected default backend
is also enabled in the build. It also enforces a full lowercase value.

This improves reproducibility and brings CMake in sync with autotools
which already worked like described above.

cmake: detect HAVE_GETADDRINFO_THREADSAFE
Based on existing autotools logic.

autotools checks for old versions of the allowlisted target OSes and
disables this feature when seeing them. In CMake we assume we're running
on newer systems and enable regardless of OS version.

autotools always runs all 3 probes for non-fast-tracked systems and
enables this feature if any one of them was successful. To save
configuration time,  CMake stops at the first successful check.

OpenBSD is not fast-tracked and then gets blocklisted as a generic BSD
system. I haven't double-checked if this is correct, but looks odd.

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.

cmake: move global headers to specific checks
Before this patch we added standard headers unconditionally to the
global list of headers used for feature checks. This is unnecessary
and also doesn't help CMake 'Generate' performance. This patch moves
these headers to each feature check where they are actually needed.
Stop using `stddef.h`, as it seems unnecessary.

I've used autotools' `m4/curl-functions.m4` to figure out these
dependencies.

Also delete checking for the C89 standard header `time.h`, that I
missed in the earlier commit.
