c-ares: fix/tidy-up macro initializations, avoid a deprecated function
- replace deprecated `ares_init()` call with `ares_init_options()`.
  Follow-up to 0d4fdbf15d #16054

- dedupe `CARES_STATICLIB` initalizations into `curl_setup.h`, to
  ensure it's defined before the first (and every) `ares.h` include and
  avoid a potential confusion.

- move `CARES_NO_DEPRECATED` from build level to `curl_setup.h`.
  To work regardless of build system.
  It is necessary because curl calls `ares_getsock()` from two places,
  of which one feeds a chain of wrappers: `Curl_ares_getsock()`,
  `Curl_resolver_getsock()`, `Curl_resolv_getsock()`.

Makefile.dist: delete
It had shorthand aliases to launch `./configure` and
`./configure --with-openssl`. The former hasn't worked for a long while
because of missing TLS.

Its `ca-bundle` and `ca-firefox` targets have been broken for 2.5 years
till recently. These targets also exist in `./configure` and have been
working all along.

Also:
- cmake: add support `curl-ca-bundle` and `curl-ca-firefox` targets.
- tests/testcurl.pl: drop obsolete build logic.

version: rename c-ares-rr to asyn-rr
Works better if we later introduce another way to do the asynch RR
resolves (together with the threaded resolver) that does not use c-ares.

asyn-thread: use c-ares to resolve HTTPS RR
Allow building with c-ares and yet use threaded resolver for the main
host A/AAAA resolving:

  `--with-ares` provides the c-ares install path and defaults to use
  c-ares for name resolving

  `--with-threaded-resolver` still uses c-ares in the build (for HTTPS)
  but uses the threaded resolver for "normal" resolves.

It works similarly for cmake: ENABLE_ARES enables ares, and if
ENABLE_THREADED_RESOLVER also is set, c-ares is used for HTTPS RR and
the threaded resolver for "normal" resolves.

HTTPSRR and c-ares-rr are new features return by curl_version_info() and
thus shown by curl -V.

The c-ares-rr feature bit is there to make it possible to distinguish
between builds using c-ares for all name resolves and builds that use
the threaded resolves for the regular name resolves and c-ares for
HTTPSRR only. "c-ares-rr" means it does not use c-ares for "plain" name
resolves.

HTTPSRR support is EXPERIMENTAL only.

cmake: drop CURL_USE_PKGCONFIG from curl-config.cmake.in
This variable was meant to be used by curl Find modules, but it turns
out it makes no sense to use those from `curl-config.cmake.in`. It means
this variable was not used before and will not be used in the future,
and therefore safe to delete.

GHA: add iOS jobs with LibreSSL, enable dependencies for Android via vcpkg
iOS:

- add jobs with autotools, CMake, CMake Xcode generator.
  The Xcode generator is >10x slower than Unix Makefiles. Keep it
  because it's the one recommended by CMake and for having its own
  quirks we may want to know about.
- build, cache and use LibreSSL for these jobs.
  With workaround for an iOS build issue fixed in master.
- make Xcode generator work by explicitly disabling code signing.
- make tests and examples build with the Xcode generator by setting
  `-DMACOSX_BUNDLE_GUI_IDENTIFIER=se.curl`, to avoid
  "Bundle identifier is missing" errors.
- cmake: disable `CURL_USE_PKGCONFIG` by default for Apple device.
- cmake: add `stdc++` library for BoringSSL and AWS-LC, with
  `OPENSSL_USE_STATIC_LIBS=ON` set.
- cmake: add workaround for Xcode generator issue, where it cannot
  handle two targets depending on one custom command. A better fix may
  be dropping `tool_hugehelp.c` and `tool_ca_embed.c` from curltool
  library. For a future PR.

Android:

- add vcpkg to Android jobs, enable dependencies.
  Assisted-by: Tal Regev via #16045
- make vcpkg work with autotools.
- pass `--with-brotli` to autotools to detect the vcpkg-supplied brotli.
- enable BoringSSL for Android and add a job with it.
- silence 457 CMake configure warnings about the Android NDK CMake
  scripts targeting freshly deprecated CMake versions.

These were much more involved than imagined. Basically nothing works out
of the box, and when combined, everything becomes a unique edge case.
autotools builds were a much easier to make work than CMake ones.

Also:

- GHA/non-native: re-sync names to be shorter and more aligned with
  other workflows.
- GHA: add `persist-credentials: false` where missing.

Unresolved issues:

- `OPENSSL_ROOT_DIR` ignored/mis-used when pointing it to LibreSSL.
  CMake seems to prepend the sysroot to the passed absolute directory.
  Found no workaround.
- CMake when combined with Android, both the Google-recommended method
  and the built-in CMake method fail to provide a way to avoid
  `pkg-config` packages at system directories. Failed to find a knob
  that can remove `/usr/include` from the search path. The workaround is
  to disable zstd. (I enabled it by default in this release, maybe
  premature?: f2adb3b6d7 #15431)
  Disabling `pkg-config` doesn't work because vcpkg dependencies do not
  link without it.
- CMake's Xcode generator is slow because each `try_compile()` feature
  check springs a new CMake + Xcode project taking a long time to run,
  just to compile single-liner C files. A known issue, with no solution.
  `-DCMAKE_MACOSX_BUNDLE=OFF` did not help, limiting build types to
  a single one (e.g. `Debug`) also had no effect.

build: stop detecting sched_yield() on Windows
On Windows a successful `sched_yield()` detection requires mingw-w64
built with POSIX threads (not Win32 threads) and GCC (not llvm/clang).
(linking to `winpthread` via custom options may also work.)

In CMake builds, it was pre-cached as unavailable before this patch.

When detected (via autotools), it got only used for Windows XP or older
targets combined with a non-GCC, non-clang compiler that doesn't support
`__builtin_ia32_pause()`, or with the Intel C compiler. According to
`lib/easy_lock.h`.

mingw-w64 only supports GCC and clang, leaving a very narrow chance when
`shed_yield()` gets called on Windows. Even then, `sched_yield()` is
implemented in `winpthread` as `Sleep(0)`, which may or not be a useful.
It's also trivial to implement locally if it is, and such rare build
combination is also deemed useful.

Thus, this patch marks `sched_yields()` permanently unavailable on the
Windows platform also with autotools, and instead of pre-caching, skip
this feature check with CMake.

This syncs `HAVE_SCHED_YIELDS` between builds methods on Windows.

"Dialog Hell", and seems to fix CMake missing to regenerate `CURL.sln`

with future versions of CMake.

At the time CMake's latest version was v2.8.10.

- drop version guards. On ancient MSVC version these macro are a no-op.
- move to `curl_setup.h` from `config-win32*.h`.
- sync macro values with CMake.
- cmake: stop setting them globally in favour of `curl_setup.h`.
- cmake: re-add these macros to `docs/examples` and `tests/http/clients`,

cmake: add librtmp Find module
The new detection method also allows to enable librtmp without using
OpenSSL as a curl TLS backend at the same time.

Also:
- implement manual version detection for librtmp.
  Version info is in hex. With CMake 3.13 and newer, extract it as a hex
  number. With earlier CMake version, just strip the leading zeroes.
  Doing more here seems overkill because librtmp has been standing
  at 2.3/2.4 for a decade now. Bumping into hex digits seems unlikely
  before deprecating CMake 3.13 support.
  librtmp advertises v2.4 via its `pkg-config` module, and v2.3 via
  its public header. The latter shows up in `curl -V` and either can
  be shown at configure-time depending on detection method.
  This isn't a curl bug.
- GHA/macos: enable rtmp in a job.
- apply the "half-detection" fix to the Find module.
  `librtmp` is also affected (in CI too), because it depends on libssl and
  libcrypto.

cmake: extend zlib's AUTO option to brotli, zstd and enable if found
- make `curl_dependency_option()` more generic.

- extend `CURL_BROTLI` and `CURL_ZSTD` options to accept
  `AUTO` in addition to existing `ON` and `OFF`.

- change `CURL_BROTLI` and `CURL_ZSTD` option default
  to `AUTO`. Was: `OFF`.
  It brings cmake behavior closer to `./configure`.
  Still different:
  - `./configure` defaults to `off` which means to check default
    locations. cmake checks more locations by default.
    (Also tried `NO_CMAKE_PATH`, but then it checked less locations.)
  - cmake returns both `brotlicommon` and `brotlidec` libs,
    while `./configure` only returns the latter.

- ci: drop explicit cmake options, that are now unnecessary.

- GHA/configure-vs-cmake: make adjustments to make tests pass.

Revert: cmake: enable CURL_USE_PKGCONFIG for cross-MINGW
This reverts commit 39c06f7883 #15005.

Combined with most Find modules now supporting `pkg-config`
(39c741b7b0 #15408) this change made
mingw-cross builds fragile by picking up OS-native components. Also
adding `/usr/include` to the header path, confusing feature detection.

cmake: add native pkg-config detection for remaining Find modules
brotli, c-ares, libpsl, libssh2, nghttp2, nghttp3, ntgcp2, zstd.

Also:

Add workaround for CMake reporting successful libssh2 detection, but
leaving the header directory empty, and causing `libssh2.h` not found
while compiling. It happens when `pkgconf` is not detecting libssh2
dependency libcrypto in Homebrew after `brew unlink openssl` (as in
GHA/macos). The workaround is to require a non-empty header directory
to consider the detection successful. This workaround may need to be
tweaked and/or applied to other Find modules.

Makefile.mk: drop in favour of autotools and cmake (MS-DOS, AmigaOS3)
`Makefile.mk` supported MS-DOS and Amiga, but `./configure` also
supported them in a better tested and more flexible way.

This patch also adds CMake support for MS-DOS/DJGPP and Amiga OS 3.

`Makefile.mk` was not maintained. Delete it in favour of first-tier
build methods.

Also include some non-MS-DOS/AmigaOS-specific tidy-up, see details at
the end of this message.

Details:

- fix/silence all MS-DOS/DJGPP build warnings and issues.
- add MS-DOS support to cmake.
  - default to `ENABLE_THREADED_RESOLVER=OFF` for MS-DOS.
  - add support for `WATT_ROOT`.
  - use static libcurl with MS-DOS.
  - fixup default CMake suffixes/prefixes for DJGPP.
  - disable hidden symbols for MS-DOS. Not supported on MS-DOS.
  - opt-in MS-DOS into `USE_UNIX_SOCKETS`.
- improve MS-DOS support in autotools.
  - default to `--disable-threaded-resolver` for MS-DOS.
- make sure to use `close_s()` (from Watt-32) with autotools and cmake.
  `Makefile.mk` used it before this patch.
- GHA: add DJGPP cmake (~30s) and autotools (~60s) build jobs.
  Also build tests and examples with cmake.
- improve AmigaOS support in autotools:
  - configure: detect `CloseSocket()` when it's a macro.
  - configure: fix `IoctlSocket` detection on AmigaOS.
  - curl-amissl.m4: pass AmiSSL libs to tests/servers.
- add AmigaOS3 support to cmake:
  - cmake: fix `HAVE_IOCTLSOCKET_CAMEL` and
    `HAVE_IOCTLSOCKET_CAMEL_FIONBIO` detections.
  - set necessary system libs.
  - add AmiSSL support.
  - inet_ntop, inet_pton: fix using it for AmigaOS. cmake detects them,
    and they did not compile with AmigaOS.
  - cmake: better sync `gethostname` detection with autotools.
    Fixes detection for AmigaOS, where `gethostname` is a macro.
  - cmake: fix `sys/utime.h` detection on AmigaOS.
  - cmake: force-disable `getaddrinfo` for AmigaOS.
  - cmake: tweak threading and static/shared default for AmigaOS.
  - cmake: rely on manual variable `AMIGA` to enable the platform.
- GHA: add AmigaOS cmake and autotools (~45s) jobs.
  Also build tests and examples with cmake.
- INSTALL: update MS-DOS and AmigaOS build instructions.
- amigaos: fix `-Wpointer-sign` and
  `zero or negative size array '_args'` in `Printf()`.
- amigaos: fix `-Wpointer-sign`
- amigaos: fix `-Wredundant-decls` `errno` and `h_errno`.
- amigaos: brute-force silence `lseek()` size warnings.
- amigaos: server/resolve: silence `-Wdiscarded-qualifiers`.
- amigaos: server/resolve: fix `-Wpointer-sign`.
- amigaos: fix `CURL_SA_FAMILY_T` type.
- nonblock: prefer `HAVE_IOCTLSOCKET_CAMEL_FIONBIO` for AmigaOS.
  `ioctl` is also detected, but fails when used. Make the above override
  it for a successful build.

- examples: fix `timeval` initialization for AmigaOS.
- examples: silence warning for AmigaOS.
- configure: fix IPv6 detection for cross-builds.
- netrc: fix to build with AmigaOS cleanly.
- buildinfo: detect and add `DOS` tag for MS-DOS builds.
- buildinfo: add `AMIGA` to buildinfo.txt in auttools.
- build: move `USE_WATT32` macro definition to cmake/configure.

Non-MS-DOS/AmigeOS-specific tidy-ups:

- configure: sync `sa_family_t` detection with cmake.
- configure: sync `ADDRESS_FAMILY` detection signals with cmake.
- doh: use `CURL_SA_FAMILY_T`.
- lib: drop mingw-specific `CURL_SA_FAMILY_T` workaround.
- cmake: extend instead of override check-specific
  configurations/requirements.
  This allows to honor global requirements added earlier.
  Necessary for AmigaOS for example.
- cmake: omit warning on disabled IPv6 for MS-DOS and AmigaOS.
  No IPv6 support on these platforms. Also sync with autotools.
- lib1960: use libcurl `inet_pton()` wrapper.
- cmake: detect LibreSSL (to match autotools).
- cmake: say the specific OpenSSL flavour detected.
- hostip: add missing `HAVE_SOCKADDR_IN6_SIN6_SCOPE_ID` guard.
- lib: simplify classic mac feature guards.

cmake: clang-cl improvements
- drop `/clang:` prefix for `-W` options for clang-cl.
  Except for `-Wall` which gets interpreted as MSVC `/Wall`
  and translated to `-Weverything`, which is undesired.
  Related: https://github.com/llvm/llvm-project/issues/102982

- include `MSVC_VERSION` in target flags.
  Useful for clang-cl builds where this information doesn't appear
  elsewhere in the cmake configure log.

- suppress `-Wlanguage-extension-token` more for clang-cl.
  This fixes clang-cl builds with default `CURL_WERROR=OFF` and
  `PICKY_COMPILER=ON`.
  This warning is enabled by `-pedantic` as a warning and by
  `-pedantic-errors` as an error. Verifiable using llvm's
  `diagtool show-enabled -pedantic test.c`.
