Ref: #12806Closes#12807
- HTTP/3 for curl using OpenSSL's own QUIC stack together
with nghttp3
- configure with `--with-openssl-quic` to enable curl to
build this. This requires the nghttp3 library
- implementation with the following restrictions:
* macOS has to use an unconnected UDP socket due to an
issue in OpenSSL's datagram implementation
See https://github.com/openssl/openssl/issues/23251
This makes connections to non-reponsive servers hang.
* GET requests will send the indicator that they have
no body in a separate QUIC packet. This may result
in processing delays or Transfer-Encodings on proxied
requests
* uploads that encounter blocks will use 100% cpu as
detection of these flow control issue is not working
(we have not figured out to pry that from OpenSSL).

Windows compilers define `_WIN32` automatically. Windows SDK headers
or build env defines `WIN32`, or we have to take care of it. The
agreement seems to be that `_WIN32` is the preferred practice here.
Make the source code rely on that to detect we're building for Windows.
Public `curl.h` was using `WIN32`, `__WIN32__` and `CURL_WIN32` for
Windows detection, next to the official `_WIN32`. After this patch it
only uses `_WIN32` for this. Also, make it stop defining `CURL_WIN32`.
There is a slight chance these break compatibility with Windows
compilers that fail to define `_WIN32`. I'm not aware of any obsolete
or modern compiler affected, but in case there is one, one possible
solution is to define this macro manually.
grepping for `WIN32` remains useful to discover Windows-specific code.
Also:
- extend `checksrc` to ensure we're not using `WIN32` anymore.
- apply minor formatting here and there.
- delete unnecessary checks for `!MSDOS` when `_WIN32` is present.

The current design of the Hyper integration requires rebuilding the
Hyper clientconn for each request. However, building the clientconn
requires resending the HTTP/2 connection preface, which is incorrect
from a protocol perspective. That in turn causes servers to send GOAWAY
frames, effectively degrading performance to "no connection reuse" in
the best case. It may also be triggering some bugs where requests get
dropped entirely and reconnects take too long.
This doesn't rule out HTTP/2 support with Hyper, but it may take a
redesign of the Hyper integration in order to make things work.

- On Windows if IPv6 is enabled but getaddrinfo is missing then #error

curl can be built with IPv6 support (ENABLE_IPV6) but without the
ability to resolve hosts to IPv6 addresses (HAVE_GETADDRINFO). On
Windows this is highly unlikely and should be considered a bad build
configuration.
Such a bad configuration has already given us a bug that was hard to
diagnose. See #12134 and #12136 for discussion.

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.)

We remove support for building curl with gskit.
- This is a niche TLS library, only running on some IBM systems
- no regular curl contributors use this backend
- no CI builds use or verify this backend
- gskit, or the curl adaption for it, lacks many modern TLS features
making it an inferior solution
- build breakages in this code take weeks or more to get detected
- fixing gskit code is mostly done "flying blind"
This removal has been advertized in DEPRECATED in Jan 2, 2023 and it has
been mentioned on the curl-library mailing list.
It could be brought back, this is not a ban. Given proper effort and
will, gskit support is welcome back into the curl TLS backend family.

Prior to this change a workaround for Windows to recv before every send
was enabled by default. The way it works is a recv is called before
every send and saves the received data, in case send fails because in
Windows apparently that can wipe out the socket's internal received
data buffer.
This feature has led to several bugs because the way libcurl operates
it waits on a socket to read or to write, and may not at all times
check for buffered receive data.
Two recent significant bugs this workaround caused:
- Broken Schannel TLS 1.3 connections (#9431)
- HTTP/2 arbitrary hangs (#10253)
The actual code remains though it is disabled by default. Though future
changes to connection filter buffering could improve the situation IMO
it's just not tenable to manage this workaround.

Partially reverts "somewhat protect Mac OS X users from using Mac OS 9

only "macintosh" is defined. Remove the additional condition that
"__MRC__" should be defined since that would only be true with the MPW
MrC compiler which prevents the use of other reasonable compilers like
the MPW SC compiler and especially the Metrowerks CodeWarrior compilers.

- Delete `makefile.dj` files. Notice the configuration details and
defaults are not retained with the new method.

options. We're also not retaining all build details from the existing
Amiga make files.
- Rename `Makefile.m32` to `Makefile.mk` to reflect that they are not
Windows/MinGW32-specific anymore.
- Add support for new `CFG` options: `-map`, `-debug`, `-trackmem`
- Set `-DNDEBUG` by default.
- Allow using `-DOS=...` in all `lib/config-*.h` headers, syncing this
with `config-win32.h`.

- Disable warning C4127 "conditional expression is constant" globally
in curl_setup.h for when building with Microsoft's compiler.
This mainly affects building with the Visual Studio project files found
in the projects dir.
Prior to this change the cmake and winbuild build systems already
disabled 4127 globally for when building with Microsoft's compiler.
Also, 4127 was already disabled for all build systems in the limited
circumstance of the WHILE_FALSE macro which disabled the warning
specifically for while(0). This commit removes the WHILE_FALSE macro and
all other cruft in favor of disabling globally in curl_setup.
Background:
We have various macros that cause 0 or 1 to be evaluated, which would
cause warning C4127 in Visual Studio. For example this causes it:
#define Curl_resolver_asynch() 1
Full behavior is not clearly defined and inconsistent across versions.
However it is documented that since VS 2015 Update 3 Microsoft has
addressed this somewhat but not entirely, not warning on while(true) for
example.
Prior to this change some C4127 warnings occurred when I built with
Visual Studio using the generated projects in the projects dir.
