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.

`stdatomic.h` and `_Atomic` were first available in gcc 4.9.0 and

Protocol handler option PROTOPT_SSL is used to setup a connection
filters. Once that is done, used `Curl_conn_is_ssl()` to check if
a connection uses SSL.
There may be other reasons to add SSL to a connection, e.g. starttls.

- setup-win32: drop duplicate `WIN32_LEAN_AND_MEAN` and `NOGDI` macros

- GHA/non-native: add Android builds, both cmake and autotools,
both NDK 21 (oldest available) and 35 (newest available)
https://github.com/actions/runner-images/blob/main/images/ubuntu/Ubuntu2404-Readme.md
It comes with a maintenance burden to bump the oldest/latest values
with CI runner updates.
- cmake: disable `CURL_USE_PKGCONFIG` by default for Android.
To avoid picking up system package by default.
- build: add `ANDROID-<NDK-LEVEL>` flag to `buildinfo.txt`.
Also detect NDK level with the CMake built-in build method:
https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html#cross-compiling-for-android
- INSTALL.md: add CMake build instructions for Android.
- INSTALL.md: make NDK levels consistent in `./configure` example.

- Fix a bug in EAGAIN handling when sending frames that led to a
corrupted last byte of the frame sent.
- Restore sanity to curl_ws_send() behaviour:
- Partial writes are reported as OK with the actual number of
payload bytes sent.
- CURLE_AGAIN is only returned when none of the payload bytes
(or for 0-length frames, not all of the frame header bytes)
could be sent.
- curl_ws_send() now behaves like a common send() call.
- Change 'ws-data' test client to allow concurrent send/recv
operations and vary frame sizes and repeat count.
- Add DEBUG env var CURL_WS_CHUNK_EAGAIN to simulate blocking
after a chunk of an encoded websocket frame has been sent.
- Add tests.
Prior to this change data corruption may occur when sending websocket
messages due to two bugs:
1) 3e64569a (precedes 8.10.0) caused a data corruption bug in the last
byte of frame of large messages.
2) curl_ws_send had non-traditional send behavior and could return
CURLE_AGAIN with bytes sent and expect the caller to adjust buffer
and buflen in a subsequent call. That behavior was not documented.

To match cmake builds.
- GHA/windows: allow autotools UWP builds.
- detect UWP and add to `buildinfo.txt`.
Consider it enabled if `CPPFLAGS` contains `-DWINSTORECOMPAT`.
- disable telnet with UWP.
- enable Unicode with UWP.
- do not use `wldap32` with UWP.
- do not enable `USE_WIN32_CRYPTO` with UWP.
- make sure to link to `ws2_32` in UWP builds.

Improved the filter implementation to be flexible in which order h3 and

When enabled in the build.
Update test2100: verify with HTTPS RR included
Adjust runtests and server/disabled.c to include "HTTPSRR" as a feature
in the test suite.
Also, decode the ALPN list in HTTPS records straight into IDs. There's
no point in storing everything in string format. Skip ALPNs we do not
support.

It lists the files built and calls `file` on them.

This typically happens if CURL_CONNECT_ONLY is used and a second

A connection "taken over" with CURL_CONNECT_ONLY cannot be ended any

- Change setopt and pretransfer to always reset URL related variables
for a CURLU handle set CURLOPT_CURLU.
This change is to ensure we are in compliance with the doc which says
CURLU handles must be able to override a URL set via CURLOPT_URL and
that if the contents of the CURLU handle changes between transfers then
the updated contents must be used.
Prior to this change, although subsequent transfers appear to be
performed correctly in those cases, the work URL `data->state.url` was
not updated. CURLINFO_EFFECTIVE_URL returns data->state.url to the user
so it would return the URL from the initial transfer which was the wrong
URL. It's likely there are other cases as well.
