build: delete checks for C89 standard headers
Delete checks and guards for standard C89 headers and assume these are
available: `stdio.h`, `string.h`, `time.h`, `setjmp.h`, `stdlib.h`,
`stddef.h`, `signal.h`.

Some of these we already used unconditionally, some others we only used
for feature checks.

Follow-up to 9c7165e96a #11918 (for `stdio.h` in CMake)

lib: use wrapper for curl_mime_data fseek callback
fseek uses long offset which does not match with curl_off_t. This leads
to undefined behavior when calling the callback and caused failure on
arm 32 bit.

Use a wrapper to solve this and use fseeko which uses off_t instead of
long.

Thanks to the nice people at Libera IRC #musl for helping finding this
out.

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

tftpd: always use curl's own tftp.h
Using the system's provided arpa/tftp.h and optimizing, GCC 12 detects
and reports a stringop-overread warning:

tftpd.c: In function ‘write_behind.isra’:
tftpd.c:485:12: warning: ‘write’ reading between 1 and 2147483647 bytes from a region of size 0 [-Wstringop-overread]
  485 |     return write(test->ofile, writebuf, count);
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In file included from tftpd.c:71:
/usr/include/arpa/tftp.h:58:30: note: source object ‘tu_data’ of size 0
   58 |                         char tu_data[0];        /* data or error string */
      |                              ^~~~~~~

This occurs because writebuf points to this field and the latter
cannot be considered as being of dynamic length because it is not
the last field in the structure. Thus it is bound to its declared
size.

This commit always uses curl's own version of tftp.h where the
target field is last in its structure, effectively avoiding the
warning.

As HAVE_ARPA_TFTP_H is not used anymore, cmake/configure checks for
arpa/tftp.h are removed.

build: streamline non-UWP wincrypt detections
- with CMake, use the variable `WINDOWS_STORE` to detect an UWP build
  and disable our non-UWP-compatible use the Windows crypto API. This
  allows to drop two dynamic feature checks.

  `WINDOWS_STORE` is true when invoking CMake with
  `CMAKE_SYSTEM_NAME` == `WindowsStore`. Introduced in CMake v3.1.

  Ref: https://cmake.org/cmake/help/latest/variable/WINDOWS_STORE.html

- with autotools, drop the separate feature check for `wincrypt.h`. On
  one hand this header has been present for long (even Borland C 5.5 had
  it from year 2000), on the other we used the check result solely to
  enable another check for certain crypto functions. This fails anyway
  with the header not present. We save one dynamic feature check at the
  configure stage.

cmake: assume wldap32 availability on Windows
This system library first shipped with Windows ME, available as an extra
install for some older releases (according to [1]). The import library
was present already in old MinGW 3.4.2 (year 2007).

Drop the feature check and its associated `HAVE_WLDAP32` variable.

To manually disable `wldap32`, you can use the `USE_WIN32_LDAP=OFF`

cmake: drop HAVE_LIBWINMM and HAVE_LIBWS2_32 feature checks
- `HAVE_LIBWINMM` was detected but unused. The `winmm` system library is
  also not used by curl, but it is by its optional dependency `librtmp`.
  Change the logic to always add `winmm` when `USE_LIBRTMP` is set. This
  library has been available since the early days of Windows.

- `HAVE_LIBWS2_32` detected `ws2_32` lib on Windows. This lib is present
  since Windows 95 OSR2 (AFAIR). Winsock1 already wasn't supported and
  other existing logic already assumed this lib being present, so delete
  the check and replace the detection variable with `WIN32` and always
  add `ws2_32` on Windows.

egd: delete feature detection and related source code

configure, cmake, lib: more form api deprecation
Introduce a --enable-form-api configure option to control its inclusion
in builds. The condition name defined for it is CURL_DISABLE_FORM_API.

Form api code is dependent of MIME: configure and CMake handle this
dependency automatically: CMake by making it a dependent option
explicitly, configure by inheriting the MIME value by default and
rejecting explicit incompatible values.

"form-api" is now a new hidden test feature.

Update libcurl modules to respect this option and adjust tests
accordingly.

cmake: support building static and shared libcurl in one go
This patch adds the ability to build a static and shared libcurl library
in a single build session. It also adds an option to select which one to
use when building the curl executable.

New build options:
- `BUILD_STATIC_LIBS`. Default: `OFF`.
  Enabled automatically if `BUILD_SHARED_LIBS` is `OFF`.
- `BUILD_STATIC_CURL`. Default: `OFF`.
  Requires `BUILD_STATIC_LIBS` enabled.
  Enabled automatically if building static libcurl only.
- `STATIC_LIB_SUFFIX`. Default: empty.
- `IMPORT_LIB_SUFFIX`. Default: `_imp` if implib filename would collide
  with static lib name (typically with MSVC) in Windows builds.
  Otherwise empty.

Also:

- Stop setting the `CURL_STATICLIB` macro via `curl_config.h`, and pass
  it directly to the compiler. This also allows to delete a condition
  from `tests/server/CMakeLists.txt`.

- Complete a TODO by following the logic used in autotools (also for
  `LIBCURL_NO_SHARED`), and set `-DCURL_STATICLIB` in `Cflags:` of
  `libcurl.pc` for _static-only_ curl builds.

- Convert an existing CI test to build both shared and static libcurl.

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.:

cmake: picky-linker fixes for openssl, ZLIB, H3 and more
- fix HTTP/3 support detection with OpenSSL/quictls built with ZLIB.
  (Requires curl be built with ZLIB option also.)

- fix HTTP/3 support detection with OpenSSL/quictls/LibreSSL and `ld`
  linker on Windows.

- fix HTTP/3 support detection with wolfSSL to automatically add
  `ws2_32` to the lib list on Windows. For all linkers.

- reposition ZLIB (and other compression) detection _after_ TLS
  detection, but before calling HTTP/3-support detection via
  `CheckQuicSupportInOpenSSL`.

  May be a regression from ebef55a61d
  May fix #10832 (Reported-by: Micah Snyder)

  This also seems to fix an odd case, where OpenSSL/quictls is correctly
  detected, but its header path is not set while compiling, breaking
  build at `src/curl_ntlm_core.c`. Reason for this remains undiscovered.

- satisfy "picky" linkers such as `ld` with MinGW, that are highly
  sensitive to lib order, by also adding brotli to the beginning of the
  lib list.

- satisfy "picky" linkers by adding certain Windows systems libs to

Note: It'd make sense to _always_ add `ws2_32`, `crypt32` (except
Windows App targets perhaps?), `bcrypt` (except old-mingw!) on Windows
at this point. They are almost always required, and if some aren't,
they are ignored by the linker with no effect on final binaries.

lib: sync guard for Curl_getaddrinfo_ex() definition and use
`Curl_getaddrinfo_ex()` gets _defined_ with `HAVE_GETADDRINFO` set. But,
`hostip4.c` _used_ it with `HAVE_GETADDRINFO_THREADSAFE` set alone. It
meant a build with the latter, but without the former flag could result
in calling this function but not defining it, and failing to link.

Patch this by adding an extra check for `HAVE_GETATTRINFO` around the
call.

Before this patch, build systems prevented this condition. Now they
don't need to.

While here, simplify the related CMake logic on Windows by setting
`HAVE_GETADDRINFO_THREADSAFE` to the detection result of
`HAVE_GETADDRINFO`. This expresses the following intent clearer than
the previous patch and keeps the logic in a single block of code:
When we have `getaddrinfo()` on Windows, it's always threadsafe.

tidy-up: process.h detection and use
This patch aims to cleanup the use of `process.h` header and the macro
`HAVE_PROCESS_H` associated with it.

- `process.h` is always available on Windows. In curl, it is required
  only for `_beginthreadex()` in `lib/curl_threads.c`.

- `process.h` is also available in MS-DOS. In curl, its only use was in
  `lib/smb.c` for `getpid()`. But `getpid()` is in fact declared by
  `unistd.h`, which is always enabled via `lib/config-dos.h`. So the
  header is not necessary.

- `HAVE_PROCESS_H` was detected by CMake, forced to 1 on Windows and
  left to real detection for other platforms.
  It was also set to always-on in `lib/config-win32.h` and
  `lib/config-dos.h`.
  In autotools builds, there was no detection and the macro was never
  set.

Based on these observations, in this patch we:

- Rework Windows `getpid` logic in `lib/smb.c` to always use the
  equivalent direct Win32 API function `GetCurrentProcessId()`, as we
  already did for Windows UWP apps. This makes `process.h` unnecessary
  here on Windows.

- Stop #including `process.h` into files where it was not necessary.
  This is everywhere, except `lib/curl_threads.c`.

  > Strangely enough, `lib/curl_threads.c` compiled fine with autotools
  > because `process.h` is also indirecty included via `unistd.h`. This
  > might have been broken in autotools MSVC builds, where the latter
  > header is missing.

- Delete all remaining `HAVE_PROCESS_H` feature guards, for they were
  unnecessary.

- Delete `HAVE_PROCESS_H` detection from CMake and predefined values
  from `lib/config-*.h` headers.

This is the single use of this variable in curl, and in a different

Also fix the warnings uncovered by the above:

- lib: add casts to silence clang warnings

cmake: sync HAVE_SIGNAL detection with autotools
`HAVE_SIGNAL` means the availability of the `signal()` function in
autotools, while in CMake it meant the availability of that function
_and_ the symbol `SIGALRM`.

The latter is not available on Windows, but the function is, which means
on Windows, autotools did define `HAVE_SIGNAL`, but CMake did not,
introducing a slight difference into the binaries.

This patch syncs CMake behaviour with autotools to look for the function
only.

The logic came with the initial commit adding CMake support to curl, so
the commit history doesn't reveal the reason behind it. In any case,
it's best to check the existence of `SIGALRM` directly in the source
before use. For now, curl builds fine with `HAVE_SIGNAL` enabled and

Fixing `ftruncate()` in turn causes a build warning/error with legacy

cmake: fix original MinGW builds
1. Re-enable `HAVE_GETADDRINFO` detection on Windows

   Commit d08ee3c83d (in 2013) added logic
   that automatically assumed `getaddrinfo()` to be present for builds
   with IPv6 enabled. As it turns out, certain toolchains (e.g. original
   MinGW) by default target older Windows versions, and thus do not
   support `getaddrinfo()` out of the box. The issue was masked for
   a while by CMake builds forcing a newer Windows version, but that
   logic got deleted in commit 8ba22ffb20.
   Since then, some CI builds started failing due to IPv6 enabled,
   `HAVE_GETADDRINFO` set, but `getaddrinfo()` in fact missing.

   It also turns out that IPv6 works without `getaddrinfo()` since commit
   67a08dca27 (from 2019, via #4662). So,
   to resolve all this, we can now revert the initial commit, thus
   restoring `getaddrinfo()` detection and support IPv6 regardless of its
   outcome.

2. Omit `bcrypt` with original MinGW

   unsupported API and do not link `bcrypt`, respectively, when using
   original MinGW.

   This patch ports that logic to CMake, fixing the link error:

build: improve OS string in CMake and config-win32.h
This patch makes CMake fill the "OS string" with the value of
`CMAKE_C_COMPILER_TARGET`, if passed. This typically contains a triplet,
the same we can pass to `./configure` via `--host=`.

For non-CMake, non-autotools, Windows builds, this patch adds the ability
to override the default `OS` value in `lib/config-win32.h`.

With these its possible to get the same OS string across the three build
systems.

This patch supersedes the earlier, partial, CMake-only solution:
435f395f3f, thus retiring the
`CURL_OS_SUFFIX` CMake option.

cmake: do not force Windows target versions
The goal of this patch is to avoid CMake forcing specific Windows
versions and rely on toolchain defaults or manual selection instead.
This gives back control to the user. This also brings CMake closer to
how autotools and `Makefile.m32` behaves in this regard.

- CMake had a setting `ENABLE_INET_PTON` defaulting to `ON`, which did
  nothing else than fixing the Windows build target to Vista. This also
  happened when the toolchain did not have Vista support (e.g. original
  MinGW), breaking such builds.

  In other environments it did not make a user-facing difference,
  because libcurl has its own pton() implementation, so it works well
  with or without Vista's inet_pton().

  This patch drops this setting. inet_pton() is now used whenever
  building for Vista or newer, either when requested manually or by
  default with modern toolchains (e.g. mingw-w64). Older envs will fall
  back to curl's pton().

  Ref: https://github.com/curl/curl/pull/9027#issuecomment-1164157604
  Ref: https://github.com/curl/curl/pull/8997#issuecomment-1164344155

- When the user did no select a Windows target version manually, stop
  explicitly targeting Windows XP, and instead use the toolchain default.

  This may pose an issue with old toolchains defaulting to pre-XP
  targets. In such case you must manually target Windows XP via:
    `-DCURL_TARGET_WINDOWS_VERSION=0x0501`
  or
    `-DCMAKE_C_FLAGS=-D_WIN32_WINNT=0x0501`

windows: improve random source
- Use the Windows API to seed the fallback random generator.

  This ensures to always have a random seed, even when libcurl is built
  with a vtls backend lacking a random generator API, such as rustls
  (experimental), GSKit and certain mbedTLS builds, or, when libcurl is
  built without a TLS backend. We reuse the Windows-specific random
  function from the Schannel backend.

- Implement support for `BCryptGenRandom()` [1] on Windows, as a
  replacement for the deprecated `CryptGenRandom()` [2] function.

  It is used as the secure random generator for Schannel, and also to
  provide entropy for libcurl's fallback random generator. The new
  function is supported on Vista and newer via its `bcrypt.dll`. It is
  used automatically when building for supported versions. It also works
  in UWP apps (the old function did not).

- Clear entropy buffer before calling the Windows random generator.

  This avoids using arbitrary application memory as entropy (with
  `CryptGenRandom()`) and makes sure to return in a predictable state
  when an API call fails.

rand: stop detecting /dev/urandom in cross-builds
- Prevent CMake to auto-detect /dev/urandom when cross-building.
  Before this patch, it would detect it in a cross-build scenario on *nix
  hosts with this device present. This was a problem for example with
  Windows builds, but it could affect any target system with this device
  missing. This also syncs detection behaviour with autotools, which also
  skips it for cross-builds.
- Also, make sure to never use the file RANDOM_FILE as entropy for libcurl's
  fallback random number generator on Windows. Windows does not have the
  concept of reading a random stream from a filename, nor any guaranteed
  non-world-writable path on disk. With this, a manual misconfiguration or
  an overeager auto-detection can no longer result in a user-controllable
  seed source.
