transfer: conn close on paused upload
- add 2 variations on test_07_42 which PAUSEs uploads
  and response connections terminating either right away
  or after the 100-continue response
- when detecting the connection being closed in transfer.c
  readwrite_data(), clear ALL send bits in data->req.keepon.
  It no longer makes send to wait for a KEEP_SEND_PAUSE or HOLD.
- in the protocol client writer add the check for incomplete
  response bodies. When an EOS is seen and the length is known,
  check that and fail if bytes are missing.

http3: quiche+ngtcp2 improvements
- quiche: error transfers that try to receive on a closed
  or draining connection
- ngtcp2: use callback for extending max bidi streams. This
  allows more precise calculation of MAX_CONCURRENT as we
  only can start a new stream when the server acknowledges
  the close - not when we locally have closed it.
- remove a fprintf() from h2-download client to avoid excess
  log files on tests timing out.

http3: extend download abort tests, fixes in ngtcp2
- fix flow handling in ngtcp2 to ACK data on streams
  we abort ourself.
- extend test_02_23* cases to also run for h3
- skip test_02_23* for OpenSSL QUIC as it gets stalled
  on progressing the connection

cw-out: improved error handling
- remember error encountered in invoking write callback and always fail
  afterwards without further invokes

tests: stabilitze test_02_23*
- h2-download now always opens the output file on first write callback
  invocation, if it will pause the transfer or not.
- Checks on output files then does not depend on the amount of data curl
  has collected for the first write.

http2: emit RST when client write fails
- When the writing of response data fails, reset the stream
  and do not return a callback error to nghttp2. That would
  be a fatal error for the connection and harm other requests.

request: paused upload on completed download, assess connection
A transfer with a completed download that is still uploading needs to
check the connection state when it is PAUSEd, since connection
close/errors would otherwise go unnoticed.

build: fix -Wconversion/-Wsign-conversion warnings
Fix remaining warnings in examples and tests which are not suppressed
by the pragma in `lib/curl_setup.h`.

older Cygwin/MSYS2 builds. Likely fixed on 2020-08-03 by:

build: enable missing OpenSSF-recommended warnings, with fixes
https://best.openssf.org/Compiler-Hardening-Guides/Compiler-Options-Hardening-Guide-for-C-and-C++.html
as of 2023-11-29 [1].

Enable new recommended warnings (except `-Wsign-conversion`):

- enable `-Wformat=2` for clang (in both cmake and autotools).
- add `CURL_PRINTF()` internal attribute and mark functions accepting
  printf arguments with it. This is a copy of existing
  `CURL_TEMP_PRINTF()` but using `__printf__` to make it compatible
  with redefinting the `printf` symbol:
  https://gcc.gnu.org/onlinedocs/gcc-3.0.4/gcc_5.html#SEC94
- fix `CURL_PRINTF()` and existing `CURL_TEMP_PRINTF()` for
  mingw-w64 and enable it on this platform.
- enable `-Wimplicit-fallthrough`.
- enable `-Wtrampolines`.
- add `-Wsign-conversion` commented with a FIXME.
- cmake: enable `-pedantic-errors` the way we do it with autotools.
  Follow-up to d5c0351055 #2747
- lib/curl_trc.h: use `CURL_FORMAT()`, this also fixes it to enable format
  checks. Previously it was always disabled due to the internal `printf`
  macro.

Fix them:

- fix bug where an `set_ipv6_v6only()` call was missed in builds with
  `--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.

- fix new `-Wformat` warnings on mingw-w64.

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`.

tests/http: make curl_setup.h the first include
This is required for the macros there to take effect for system
libraries. Specifically, including the system libraries first led to
warnings about `_FILE_OFFSET_BITS` being redefined in curl_config.h on
the Solaris autobuilds for ws-data.c and ws-pingpong.c.
Also make the curl includes come first for the other source files here
for consistency.

tests/http: more tests with specific clients
- Makefile support for building test specific clients in tests/http/clients
- auto-make of clients when invoking pytest
- added test_09_02 for server PUSH_PROMISEs using clients/h2-serverpush
- added test_02_21 for lib based downloads and pausing/unpausing transfers

curl url parser:
- added internal method `curl_url_set_authority()` for setting the
  authority part of a url (used for PUSH_PROMISE)

http2:
- made logging of PUSH_PROMISE handling nicer

Placing python test requirements in requirements.txt files
- separate files to base test suite and http tests since use
  and module lists differ
- using the files in the gh workflows

websocket test cases, fixes for we and bufq
- bufq: account for spare chunks in space calculation
- bufq: reset chunks that are skipped empty
- ws: correctly encode frames with 126 bytes payload
- ws: update frame meta information on first call of collect
