In 8.4.0 we deleted `_mingw.h` as part of purging old-mingw support.
Turns out `_mingw.h` had the side-effect of setting a default
`_WIN32_WINNT` value expected by `lib/config-win32.h` to enable
`getaddrinfo` support in `Makefile.mk` mingw-w64 builds. This caused
disabling support for this unless specifying the value manually.
Restore this header and update its comment to tell why we continue
to need it.
This triggered a regression in official Windows curl builds starting
with 8.4.0_1. Fixed in 8.4.0_6. (8.5.0 will be using CMake.)

- eliminate the terrible hack in cf-socket.c to guess when
this happened and try not closing the socket again.

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.

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.

Closes#12194
Connection filter had a `get_select_socks()` method, inspired by the
various `getsocks` functions involved during the lifetime of a
transfer. These, depending on transfer state (CONNECT/DO/DONE/ etc.),
return sockets to monitor and flag if this shall be done for POLLIN
and/or POLLOUT.
Due to this design, sockets and flags could only be added, not
removed. This led to problems in filters like HTTP/2 where flow control
prohibits the sending of data until the peer increases the flow
window. The general transfer loop wants to write, adds POLLOUT, the
socket is writeable but no data can be written.
This leads to cpu busy loops. To prevent that, HTTP/2 did set the
`SEND_HOLD` flag of such a blocked transfer, so the transfer loop cedes
further attempts. This works if only one such filter is involved. If a
HTTP/2 transfer goes through a HTTP/2 proxy, two filters are
setting/clearing this flag and may step on each other's toes.
Connection filters `get_select_socks()` is replaced by
`adjust_pollset()`. They get passed a `struct easy_pollset` that keeps
up to `MAX_SOCKSPEREASYHANDLE` sockets and their `POLLIN|POLLOUT`
flags. This struct is initialized in `multi_getsock()` by calling the
various `getsocks()` implementations based on transfer state, as before.
After protocol handlers/transfer loop have set the sockets and flags
they want, the `easy_pollset` is *always* passed to the filters. Filters
"higher" in the chain are called first, starting at the first
not-yet-connection one. Each filter may add sockets and/or change
flags. When all flags are removed, the socket itself is removed from the
pollset.
Example:
* transfer wants to send, adds POLLOUT
* http/2 filter has a flow control block, removes POLLOUT and adds
POLLIN (it is waiting on a WINDOW_UPDATE from the server)
* TLS filter is connected and changes nothing
* h2-proxy filter also has a flow control block on its tunnel stream,
removes POLLOUT and adds POLLIN also.
* socket filter is connected and changes nothing
* The resulting pollset is then mixed together with all other transfers
and their pollsets, just as before.
Use of `SEND_HOLD` is no longer necessary in the filters.
All filters are adapted for the changed method. The handling in
`multi.c` has been adjusted, but its state handling the the protocol
handlers' `getsocks` method are untouched.
The most affected filters are http/2, ngtcp2, quiche and h2-proxy. TLS
filters needed to be adjusted for the connecting handshake read/write
handling.
No noticeable difference in performance was detected in local scorecard
runs.

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#L296https://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#L290https://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`.

Currently the verbose output does not include which algorithms are used
for the signature and key exchange when using OpenSSL. Including the
algorithms used will enable better debugging when working on using new
algorithm implementations. Know what algorithms are used has become more
important with the fast growing research into new quantum-safe
algorithms.
This implementation includes a build time check for the OpenSSL version
to use a new function that will be included in OpenSSL 3.2 that was
introduced in openssl/openssl@6866824

inspection of previous test runs show none of those being found in pure
Windows CI builds.
With this fixed, they can be used to detect the handle64.exe program

run with the error
