cookie: avoid saving a cookie file if no transfer was done
Because parts of the cookie loading happens on transfer start the
in-memory cookie jar risks being incomplete and then a save might
wrongly truncate the target file.

asyn-thrdd: drop pthread_cancel
Remove use of pthread_cancel in asnyc threaded resolving. While there
are system where this works, others might leak to resource leakage
(memory, files, etc.). The popular nsswitch is one example where resolve
code can be dragged in that is not prepared.

The overall promise and mechanism of pthread_cancel() is just too
brittle and the historcal design of getaddrinfo() continues to haunt us.

threaded-resolver: fix shutdown
Changed strategy to start up and terminate resolver thread.

When starting up:

Start the thread with mutex acquired, wait for signal from thread that
it started and has incremented the ref counter. Thread set
pthread_cancel() to disabled before that and only enables cancelling
during resolving itself. This assure that the ref counter is correct and
the unlinking of the resolve context always happens.

When shutting down resolving:

If ref counting shows thread has finished, join it, free everything. If
thread has not finished, try pthread_cancel() (non Windows), but keep
the thread handle around.

When destroying resolving:

Shutdown first, then, if the thread is still there and 'quick_exit' is
not set, join it and free everything. This might occur a delay if
getaddrinfo() hangs and cannot be interrupted by pthread_cancel().

Destroying resolving happens when another resolve is started on an
easy handle or when the easy handle is closed.

Add test795 to check that connect timeout triggers correctly
when resolving is delayed. Add debug env var `CURL_DNS_DELAY_MS`
to simulate delays in resolving.

Fix test1557 to set `quick_exit` and use `xxx.invalid` as domain
instead of `nothing` that was leading to hangers in CI.

websocket: support CURLOPT_READFUNCTION
Add support for CURLOPT_READFUNCTION with WebSocket urls when *not* in
connect-only mode, e.g. when using curl_multi_perform.

Install the callback function and set CURLOPT_UPLOAD. Return
CURL_READFUNC_PAUSE when having nothing more to send and unpause the
transfer when more data is ready.

This will send the read bytes in a WebSocket BINARY frame.

Add support for this mode in the pytest "ws_data" client and have all
tests run in 'curl_ws_send/recv' and 'peform' mode as well.

Add `curl_ws_start_frame()`. Document, cover in libcurl-ws.md and
explain the READFUNCTION mode for websockets.

Add example `websocket-updown` for this.

tests: merge clients into libtests, drop duplicate code
libtests and clients were built the same way after recent overhauls.
libtests are used by runtests, clients by pytests.

Merge clients into libtests, aligning their entry function signature,
dropping common utility functions, and simplifying the build.

Note: After this patch `CURLDEBUG` applies to cli tests, when enabled.

Also:
- lib552: drop local copy-paste debug callback in favor of testtrace.
- lib552: drop local copy-paste dump function in favor of testtrace.
- clients: use `long` for HTTP version, drop casts.
- clients: replace local dump function in favor of testrace clone.
- sync cli test entry function prototype with libtests'.
- h2_serverpush: replace local trace callback with testtrace.
- de-duplicate 3 websocket close, ping, ping, functions. Kept the pong
  iteration from `ws_pingpong`. Note: the pong clone in `lib2304` was
  returning an error when `curl_ws_recv()` returned non-zero and
  the payload matched the expected one anyway. After this patch, this
  case returns success, as it does in `ws_pingpong`.
  `lib2304` keeps passing, but I'm not sure if the previous behavior
  was intentional.
- display full value in websocket close, ping, pong, drop casts.

lib517: use LL 64-bit literals & re-enable a test case (time_t)
Suffix two 64-bit `time_t` test literals with `LL` to make them compile
with mingw-w64 x86_64 in C89 (the default) mode. Possibly other old gcc
compilers are affected (e.g. mips gcc 4.9.4, power gcc 15.1.0), but
could not pinpoint the exact rules. This also fixes a compiler warning
and test failure with MSVC, allowing to re-enable a disabled test case.

`LL` is not C89, but used in the code before this patch, which tells
it's safe to use.

Also display expected / actual timestamp values as `curl_off_t` instead
of `long`, making them work with 64-bit timestamps.

This was triggered by this issue seen while testing mingw-w64 gcc 4.8.1:
```
tests/libtest/lib517.c:147:5: error: this decimal constant is unsigned only in ISO C90
     {"Sun, 06 Nov 2044 08:49:37 GMT", (time_t) 2362034977 },

cmake: omit linking duplicate/unnecessary libs to tests & examples
Before this patch we explicitly linked the full list of libcurl
dependency libs to tests and examples via `CURL_LIBS`. This was
redundant, because test and example code do not directly use these
dependency libs and for indirect use they are implicitly passed
via libcurl as needed. After this patch, tests and examples only link
explicitly to system libs (e.g. socket).

Also bringing it closer to how `./configure` does this.

Borrow the variable name `CURL_NETWORK_AND_TIME_LIBS` from
`./configure`. However, its content is not exactly the same. With cmake
it also holds `pthread`, but doesn't hold AmiSSL.

build: extend GNU C guards to clang where applicable, fix fallouts
Some GNU C version guards implicitly include the clang compiler, because
clang reports itself as GCC 4.2.1.

This implicit inclusion doesn't happen if the guard requires a GCC
version above 4.2.1.

Fix two such guards to explicitly include clang where it does support
the guarded feature:

- curl/curl.h: use `typecheck-gcc.h` with clang.
  llvm clang v14+ supports this. The corresponding Apple clang version
  is also v14.
  Ref: https://en.wikipedia.org/wiki/Xcode#Toolchain_versions
  Apple clang v14 tested OK in CI:
  https://github.com/curl/curl/actions/runs/16353901480/job/46207437204

- tool_urlglib: use `__builtin_mul_overflow()` with clang v8+.
  llvm clang v3.8+ supports this, but to accommodate for Apple clang,
  start with v8, the Apple version having the mainline v3.8 feature set.

Also fix compile warnings triggered by the above:
- lib1912: fix duplicate `;`:
  ```

lib1560: fix memory leak when run without UTF-8 support
The issue is missed in CI, because valgrind jobs all run with UTF-8
support.

Fixing:
```
test 1560...[URL API]
 valgrind ERROR ==13362== 104 bytes in 1 blocks are definitely lost in loss record 1 of 1
==13362==    at 0x484D953: calloc (in /usr/libexec/valgrind/vgpreload_memcheck-amd64-linux.so)

tidy-up: Curl_thread_create() callback return type
Replace repeat `#ifdef` code with a macro for the return type of
the thread function.

Also:
- always define `CURL_STDCALL`, allowing to use it without guards.
- lib1307: drop single-use macro `CAINFO`.

GHA/checksrc: expand spellcheck, fix issues found
- codespell: break logic out into its own runnable script. Allowing
  to run it on local machines.
- codespell: install via `pip`, bump to latest version.
- codespell: show version number in CI log.
- codespell: drop no longer needed word exception: `msdos`.
- codespell: include all curl source tree, except `packages` and
  `winbuild`. Drop an obsolete file exclusion.
- add new spellchecker job using the `typos` tool. It includes
  the codespell dictionary and a couple more. Use linuxbrew to install
  it. This takes 10 seconds, while installing via `cargo` from source
  would take over a minute.
- codespell: introduce an inline ignore filter compatible with `cspell`
  Make `typos` recognize it, too. Move single exceptions inline.

Fix new typos found. Also rename variables and words to keep
spellchecking exceptions at minumum. This involves touching some tests.
Also switch base64 strings to `%b64[]` to avoid false positives.

test1560: skip some URLs if UTF-8 is not supported
Debian CI found that `lib1560` implements tests that will fail when
UTF-8 isn't supported.  We can detect that with `nl_langinfo` and skip
the specific URLs that fail (i.e., those whose `getflags` are either
`CURLU_PUNYCODE` or `CURLU_PUNY2IDN`).
