cmake: detect nettle when building with GnuTLS
`nettle` is a direct dependency of curl, when building with GnuTLS.
Add a new `Find` module to detect it.

Also:
- GHA/macos: drop `nettle` hack no longer necessary.
- add `nettle` to `libcurl.pc`.
- also add `nettle` to `libcurl.pc` in autotools builds.

configure: fix SystemConfiguration detection
Before this patch, `SystemConfiguration` detection failed due to this
error when compiling the detection snippet:
```
/Applications/Xcode_15.3.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/TargetConditionals.h:140:50: error: missing binary operator before token "("
  140 | #if !defined(__has_extension) || !__has_extension(define_target_os_macros)
      |                                                  ^
```
Ref: https://github.com/curl/curl/actions/runs/9821817534/job/27117929218#step:6:1079

It occured with gcc-11 when combined with macOS SDK 14.4 and 14.5
(default SDKs in Xcode 15.3 and 15.4 respectively). It did not happen
with earlier releases.

Despite the failure in `./configure`, `lib/macos.c` compiled with
Apple's `TargetConditionals.h` just fine.

Turns out that including the `sys/types.h` header before the SDK
header fixes the error and makes the detection snippet compile.

build: sync warning options between autotools, cmake & compilers
- cmake: enable Apple-specific `-Werror=partial-availability` to match
  autotools.

- autotools: enable `-pedantic-errors` with llvm/clang to match gcc and
  CMake.

- autotools: enable `-Werror-implicit-function-declaration` for
  llvm/clang to match gcc.

- cmake: enable `-Werror-implicit-function-declaration` to match
  autotools.

- move `-Wpointer-bool-conversion` from autotools to the local file
  (`sectransp.c`) it was meant to apply. This way it applies to all
  build methods.

- autotoos: show `CURL_CFLAG_EXTRAS` in the `./configure` summary.
  (it may contain `-Werror` and/or `-pedentic-errors`.)

curl-rustls.m4: add pkg-config support to rustls detection
Based on the existing openssl pkg-config detection, this commit tries to
use pkg-config to find `rustls` then falls back to the current approach
if that fails.

We use the following logic:

- if no path is provided, just use pkg-config, if it's not there we have
  a problem!
- if a path is provided, try pkg-config
  + if pkg-config fails, try and find rustls directly

http3: initial support for OpenSSL 3.2 QUIC stack
- 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).

- enable `-Wformat=2` for clang (in both cmake and autotools).
- add `CURL_PRINTF()` internal attribute and mark functions accepting

- enable `-Wtrampolines`.
- add `-Wsign-conversion` commented with a FIXME.

  `--disable-verbose` / `CURL_DISABLE_VERBOSE_STRINGS=ON`.
- add internal `FALLTHROUGH()` macro.
- replace obsolete fall-through comments with `FALLTHROUGH()`.
- fix fallthrough markups: Delete redundant ones (showing up as
  warnings in most cases). Add missing ones. Fix indentation.
- silence `-Wformat-nonliteral` warnings with llvm/clang.
- fix one `-Wformat-nonliteral` warning.
- fix new `-Wformat` and `-Wformat-security` warnings.
- fix `CURL_FORMAT_SOCKET_T` value for mingw-w64. Also move its
  definition to `lib/curl_setup.h` allowing use in `tests/server`.
- lib: fix two wrongly passed string arguments in log outputs.

build: add more picky warnings and fix them
Enable more picky compiler warnings. I've found these options in the
nghttp3 project when implementing the CMake quick picky warning
functionality for it [1].

`-Wunused-macros` was too noisy to keep around, but fixed a few issues
it revealed while testing.

- autotools: reflect the more precisely-versioned clang warnings.
  Follow-up to 033f8e2a08 #12324
- autotools: sync between clang and gcc the way we set `no-multichar`.
- autotools: avoid setting `-Wstrict-aliasing=3` twice.
- autotools: disable `-Wmissing-noreturn` for MSYS gcc targets [2].
  It triggers in libtool-generated stub code.

- lib/timeval: delete a redundant `!MSDOS` guard from a `WIN32` branch.

- lib/curl_setup.h: delete duplicate declaration for `fileno`.
  Added in initial commit ae1912cb0d
  (1999-12-29). This suggests this may not be needed anymore, but if
  it does, we may restore this for those specific (non-Windows) systems.
- lib: delete unused macro `FTP_BUFFER_ALLOCSIZE` since
  c1d6fe2aaa.
- lib: delete unused macro `isxdigit_ascii` since
  f65f750742.
- lib/mqtt: delete unused macro `MQTT_HEADER_LEN`.
- lib/multi: delete unused macro `SH_READ`/`SH_WRITE`.
- lib/hostip: add `noreturn` function attribute via new `CURL_NORETURN`
  macro.
- lib/mprintf: delete duplicate declaration for `Curl_dyn_vprintf`.
- lib/rand: fix `-Wunreachable-code` and related fallouts [3].
- lib/setopt: fix `-Wunreachable-code-break`.
- lib/system_win32 and lib/timeval: fix double declarations for
  `Curl_freq` and `Curl_isVistaOrGreater` in CMake UNITY mode [4].
- lib/warnless: fix double declarations in CMake UNITY mode [5].
  This was due to force-disabling the header guard of `warnless.h` to
  to reapply it to source code coming after `warnless.c` in UNITY
  builds. This reapplied declarations too, causing the warnings.
  Solved by adding a header guard for the lines that actually need
  to be reapplied.
- lib/vauth/digest: fix `-Wunreachable-code-break` [6].
- lib/vssh/libssh2: fix `-Wunreachable-code-break` and delete redundant
  block.
- lib/vtls/sectransp: fix `-Wunreachable-code-break` [7].
- lib/vtls/sectransp: suppress `-Wunreachable-code`.
  Detected in `else` branches of dynamic feature checks, with results
  known at compile-time, e.g.
  ```c
  if(SecCertificateCopySubjectSummary)  /* -> true */
  ```
  Likely fixable as a separate micro-project, but given SecureTransport
  is deprecated anyway, let's just silence these locally.
- src/tool_help: delete duplicate declaration for `helptext`.
- src/tool_xattr: fix `-Wunreachable-code`.
- tests: delete duplicate declaration for `unitfail` [8].
- tests: delete duplicate declaration for `strncasecompare`.
- tests/libtest: delete duplicate declaration for `gethostname`.
  Originally added in 687df5c8c3
  (2010-08-02).
  Got complicated later: c49e9683b8
  If there are still systems around with warnings, we may restore the
  prototype, but limited for those systems.
- tests/lib2305: delete duplicate declaration for
  `libtest_debug_config`.
- tests/h2-download: fix `-Wunreachable-code-break`.

autotools: stop setting -std=gnu89 with --enable-warnings
Do not alter the C standard when building with `--enable-warnings` when
building with gcc.

On one hand this alters warning results compared to a default build.
On the other, it may produce different binaries, which is unexpected.

Also fix new warnings that appeared after removing `-std=gnu89`:

- include: fix public curl headers to use the correct printf mask for
  `CURL_FORMAT_CURL_OFF_T` and `CURL_FORMAT_CURL_OFF_TU` with mingw-w64
  and Visual Studio 2013 and newer. This fixes the printf mask warnings
  in examples and tests. E.g. [1]

- conncache: fix printf format string [2].

- http2: fix potential null pointer dereference [3].
  (seen on Slackware with gcc 11.)

- libssh: fix printf format string in SFTP code [4].
  Also make MSVC builds compatible with old CRT versions.

- libssh2: fix printf format string in SFTP code for MSVC.
  Applying the same fix as for libssh above.

- unit1395: fix `argument is null` and related issues [5]:
  - stop calling `strcmp()` with NULL to avoid undefined behaviour.
  - fix checking results if some of them were NULL.
  - do not pass NULL to printf `%s`.

- ci: keep a build job with `-std=gnu89` to continue testing for
  C89-compliance. We can apply this to other gcc jobs as needed.

tidy-up: use OPENSSL_VERSION_NUMBER
Uniformly use `OPENSSL_VERSION_NUMBER` to check for OpenSSL version.
Before this patch some places used `OPENSSL_VERSION_MAJOR`.

Also fix `lib/md4.c`, which included `opensslconf.h`, but that doesn't
define any version number in these implementations: BoringSSL, AWS-LC,
LibreSSL, wolfSSL. (Only in mainline OpenSSL/quictls). Switch that to
`opensslv.h`. This wasn't causing a deeper problem because the code is
looking for v3, which is only provided by OpenSSL/quictls as of now.

According to https://github.com/openssl/openssl/issues/17517, the macro
`OPENSSL_VERSION_NUMBER` is safe to use and not deprecated.

build: delete support bits for obsolete Windows compilers
- Pelles C: Unclear status, failed to obtain a fresh copy a few months
  ago. Possible website is HTTP-only. ~10 years ago I left this compiler
  dealing with crashes and other issues with no response on the forum
  for years. It has seen some activity in curl back in 2021.
- LCC: Last stable release in September 2002.
- Salford C: Misses winsock2 support, possibly abandoned? Last mentioned
  in 2006.
- Borland C++: We dropped Borland C++ support in 2018.
- MS Visual C++ 6.0: Released in 1998. curl already requires VS 2010
  (or possibly 2008) as a minimum.

build: delete HAVE_STDINT_H and HAVE_INTTYPES_H
We use `stdint.h` unconditionally in all places except one. These uses
are imposed by external dependencies / features. nghttp2, quic, wolfSSL
and `HAVE_MACH_ABSOLUTE_TIME` do require this C99 header. It means that
any of these features make curl require a C99 compiler. (In case of
MSVC, this means Visual Studio 2010 or newer.)

This patch changes the single use of `stdint.h` guarded by
`HAVE_STDINT_H` to use `stdint.h` unconditionally. Also stop using
`inttypes.h` as an alternative there. `HAVE_INTTYPES_H` wasn't used
anywhere else, allowing to delete this feature check as well.

cmake: pre-fill rest of detection values for Windows
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#L296
    https://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#L290
    https://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`.

- show CMake version via `CMakeLists.txt`.
  Credit to the `zlib-ng` project for the idea:
  61e181c8ae/CMakeLists.txt (L7)

- make `CMake/CurlTests.c` pass `checksrc`.

- `CMake/WindowsCache.cmake` tidy-ups.

- replace `WIN32` guard with `_WIN32` in `CMake/CurlTests.c`.

build: do not publish HAVE_BORINGSSL, HAVE_AWSLC macros
Syncing this up with CMake.

Source code uses the built-in `OPENSSL_IS_AWSLC` and
`OPENSSL_IS_BORINSSL` macros to detect BoringSSL and AWS-LC. No help is
necessary from the build tools.

The one use of `HAVE_BORINGSSL` in the source turned out to be no longer
necessary for warning-free BoringSSL + Schannel builds. Ref: #1610 #2634

autotools detects this anyway for display purposes.
CMake detects this to decide whether to use the BoringSSL-specific
crypto lib with ngtcp2. It detects AWS-LC, but doesn't use the detection
result just yet (planned in #12066).

autotools: restore HAVE_IOCTL_* detections
This restores `CURL_CHECK_FUNC_IOCTL` detection. I deleted it in
4d73854462 and
c3456652a0 (2022-08), because the
`HAVE_IOCTL` result it generated was unused in the source. But,
I did miss the fact that this had two dependent checks:
`CURL_CHECK_FUNC_IOCTL_FIONBIO`,
`CURL_CHECK_FUNC_IOCTL_SIOCGIFADDR` that we do actually need:
`HAVE_IOCTL_FIONBIO`, `HAVE_IOCTL_SIOCGIFADDR`.

CURL_OSX_CALL_COPYPROXIES is renamed to CURL_MACOS_CALL_COPYPROXIES and
is now only defined when SCDynamicStoreCopyProxies will actually be
called. Previously, it was defined when ENABLE_IPV6 was not defined but
SCDynamicStoreCopyProxies is not called in that case.

TARGET_OS_OSX is only defined in the macOS 10.12 SDK and later and only
when dynamic targets are enabled. TARGET_OS_MAC is always defined but
means any Mac OS or derivative including macOS, iOS, tvOS, and watchOS.
TARGET_OS_IPHONE means any Darwin OS other than macOS.
