urlapi: verify the last letter of a scheme when set explictly
A logic error made the function not check the last character, which thus
could make it accept invalid schemes.

cookie: flush better
The cookie flushing (saving to a cookie jar) should only be done if a
transfer has been started. This is now done by checking the
cookies->running field, which is not reset in curl_easy_reset() so the
saving works correctly even after a call to that.

curlx: curlx_strcopy() instead of strcpy()
This function REQUIRES the size of the target buffer as well as the
length of the source string. Meant to make it harder to do a bad
strcpy().

Removes 23 calls to strcpy().

localtime: detect thread-safe alternatives and use them
- add local API `toolx_localtime()` to wrap the banned function
  `localtime()`. Used from libcurl, libtests and test servers.
- auto-detect and use `localtime_r()` where available (e.g. Linux).
  Also to support multi-threading.
- use `localtime_s()` on Windows. It requires MSVC or mingw-w64 v4+.
  Also to support multi-threading.
  Use local workaround to also support mingw-w64 v3.
- add `src/toolx` to keep internal APIs used by the curl tool and tests,
  but not by libcurl. `toolx_localtime()` is the first API in it.
- replace `localtime()` calls with `toolx_localtime()`.
  Except in examples.
- note Windows XP's default `msvcrt.dll` doesn't offer secure CRT APIs.
  XP likely needs a newer version of this DLL, or may not run.
- note that `localtime()` mirrors `gmtime()`, with the difference that
  `gmtime()`'s internal wrapper lives in curlx.

Also:
- drop redundant `int` casts.

build: avoid overriding system symbols for fopen functions
By introducing wrappers for them in the curlx namespace:
`curlx_fopen()`, `curlx_fdopen()`, `curlx_fclose()`.

The undefine/redefine/`(function)()` methods broke on systems
implementing these functions as macros. E.g. AIX 32-bit's `fopen()`.

Also:
- rename `lib/fopen.*` to `lib/curl_fopen.*` (for `Curl_fopen()`)
  to make room for the newly added `curlx/fopen.h`.
- curlx: move file-related functions from `multibyte.c` to `fopen.c`.
- tests/server: stop using the curl-specific `fopen()` implementation
  on Windows. Unicode isn't used by runtests, and it isn't critical to
  run tests on longs path. It can be re-enabled if this becomes
  necessary, or if the wrapper receives a feature that's critical for
  test servers.

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.

tests: move curlcheck.h to libtest as unitcheck.h
To simplify dependencies, and sync tunits and units builds further.

`curlcheck.h` already depended on logic implemented within libtests:
it referenced a global variable (`unitfail`) defined in `first.c` and
declared in `test.h`.

Also:
- rename to `unitcheck.h` to indicate it's meant for unit tests.
- make `unitcheck.h` include `first.h` instead of `test.h`.
  This brings header use closer to libtests. It also includes
  `curlx/curlx.h` for all unit tests by default now.
- move `unitfail` declaration from `test.h` to `first.h`.
  To match its definition in `first.c`.

tests: move GSS-API dynamic stub into debug-mode libcurl
Replace the `libstubgss.so`-based overload solution with one built into
libcurl at compile-time.

The previous, `LD_PRELOAD`-based, solution was non-portable, allowlisted
for Linux, BSD and Solaris. It also required non-debug builds, which
turned out to be an accidental condition:
7d342c723c. It also required a curl tool
built against a shared libcurl. Detecting this condition wasn't always
accurate, e.g. with certain cmake configurations.

The overload solution also didn't work on macOS, though it theoretically
should have:
- #17653
- #2394

Experiments on making the overload solution work in more envs:
- #17759
  That revealed that it also did not work on NetBSD, in CI.

The replacement solution is overloading the necessary GSS-API functions
for test 2056 and 2057 at compile time. It requires a debug-enabled curl
build (due to its insecure nature).

This makes these tests run on all platforms. Including most GSS jobs in
CI, that are running tests. (the exception is old-linux, non-debug jobs,
where it felt overkill to enable debug for this.)

The refactored GSS stub code needs to overload less than before because
it's free to use the official GSS API. (This didn't work with
the overload solution on Alpine for example). It can also use libcurl
functions, allowing to replace `snprintf()` with `msnprintf()`.

OS/400 is also overloading GSS API functions. I haven't tested how this
works after this PR. In theory it should, because this PR doesn't rely
on preprocessor overrides.

Note that for future GSS tests, it may be necessary to stub these GSS
API functions: `gss_inquire_context()`, `gss_unwrap()`, `gss_wrap()`.
They are on codepaths not (yet) touched by tests.

Also:
- stub-gss: check for token buffer overrun.
- stub-gss: replace size macros with `sizeof()`.
- GHA: enable debug for some jobs with GSS.
- GHA/linux: ignore results for 2056 and 2057 in the valgrind job.
  They leak the same way as seen with 2077 and 2078.

cmake: build stubgss library for libtests to match autotools
Used by test 2056 and 2057, in a way that's Linux- & autotools-specific.
This patch builds it for all Unix, syncing cmake with autotools.

Adapt the two tests to find the library in CMake builds as well.

Tested OK on Linux. (CI does not test this. The corresponding jobs build
in debug mode, while the `LD_PRELOAD` feature is locked to non-debug.)

On macOS it didn't load without building everything for aarch64e arch:
"../bld/tests/libtest/libstubgss.dylib' (mach-o file, but is
an incompatible architecture (have 'arm64', need 'arm64e'))"
With that fixed it still did not load correctly and/or the tests did not
pass. So, for macOS these tests remain disabled.

Also:
- GHA/macos: build for aarch64e. (recognized by Apple clang as of this
  patch. llvm and gcc fall back to aarch64.)

66d35ee5d4 lib: avoid reusing unclean connection
When `curl_easy_cleanup()` is invoked while still being part
of a multi handle, the code will auto-remove it. But since the
connection was detached first, the code in
`curl_multi_remove_handle()` that invalidates dirty connections
did not bite.

Attach the connection *after* the possible remove from a multi
handle, so that connection reuse can be prevented.

Add test753 to reproduce and verify the fix. This required adding
the new debug env var CURL_FTP_PWD_STOP, to have a transfer return
from multi_perform() early with a connection that does not show
and pending input.

tests: always make bundles, adapt build and tests
Make test bundles the default. Drop non-bundle build mode.
Also do all the optimizations and tidy-ups this allows, simpler builds,
less bundle exceptions, streamlined build mechanics.

Also rework the init/deinit macro magic for unit tests. The new method
allows using unique init/deinit function names, and calling them with
arguments. This is in turn makes it possible to reduce the use of global
variables.

Note this drop existing build options `-DCURL_TEST_BUNDLES=` from cmake
and `--enable-test-bundles` / `--disable-test-bundles` from autotools.

Also:
- rename test entry functions to have unique names: `test_<testname>`
  This removes the last exception that was handled in the generator.
- fix `make dist` to not miss test sources with test bundles enabled.
- sync and merge `tests/mk-bundle.pl` into `scripts/mk-unity.pl`.
- mk-unity.pl: add `--embed` option and use it when `CURL_CLANG_TIDY=ON`
  to ensure that `clang-tidy` does not miss external test C sources.
  (because `clang-tidy` ignores code that's #included.)

- tests: reduce symbol scopes, global macros, other fixes and tidy-ups.
- tool1621: fix to run, also fix it to pass.
- sockfilt: fix Windows compiler warning in certain unity include order,

  - b) A new fragmented message is started (0x81/0x01/0x82/0x02...)
    before the ongoing fragmented message has terminated.

- Made logs for invalid opcodes easier to understand.
- Moved noisy logs to the `CURL_TRC_WS` log level.
- Unified the prefixes for WebSocket log messages: `[WS] ...`

- Add env var `CURL_WS_FORCE_ZERO_MASK` in debug builds.

  - If set, it forces the bit mask applied to outgoing payloads to
    0x00000000, which effectively means the payload is not masked at
    all. This drastically simplifies defining the expected `<protocol>`
    data in test cases.

- 2719: Fragmented messages _(part. replaces 2311)_
- 2720: Fragmented messages with empty fragments
- 2721: Fragmented messages with interleaved pong
- 2722: Invalid fragmented message without initial frame
- 2723: Invalid fragmented message without final frame

- 2305: curl_ws_recv() loop reading three larger frames
  - This test involuntarily sent an invalid sequence of opcodes (0x01...,0x01...,0x81...) , but neither libcurl nor the test caught this! The correct sequence was tested in 2311 (0x01...,0x00...,0x80...). See below for 2311.
  - Validation of the opcode sequence was added to libcurl and is now tested in 2723.
  - Superseded by 2719 (fragmented message) and 2707 (large frames).
- 2307: overlong PING payload
  - The tested PING payload length check was actually missing, but the test didn't catch this since it involuntarily sent an invalid opcode (0x19... instead of 0x89...) so that the expected error occurred, but for the wrong reason.
  - Superseded by 2713.
- 2310: unknown reserved bit set in frame header
  - Superseded by 2703 and extended by 2704 and 2705.
- 2311: curl_ws_recv() read fragmented message
  - Superseded by 2719 (fragmented message) and 2707 (large frames).
- 2312: WebSockets no auto ping
  - Superseded by 2709.

- No tests for `CURLOPT_WRITEFUNCTION`.
- No tests for sending of invalid frames/fragments.

curlx: move into to curlx/
Move curlx_ functions into its own subdir.

The idea is to use the curlx_ prefix proper on these functions, and use
these same function names both in tool, lib and test suite source code.
Stop the previous special #define setup for curlx_ names.

The printf defines are now done for the library alone. Tests no longer
use the printf defines. The tool code sets its own defines. The printf
functions are not curlx, they are publicly available.

The strcase defines are not curlx_ functions and should not be used by
tool or server code.

dynbuf, warnless, base64, strparse, timeval, timediff are now proper
curlx functions.

When libcurl is built statically, the functions from the library can be
used as-is. The key is then that the functions must work as-is, without
having to be recompiled for use in tool/tests. This avoids symbol
collisions - when libcurl is built statically, we use those functions
directly when building the tool/tests. When libcurl is shared, we
build/link them separately for the tool/tests.

vtsl: eliminate 'data->state.ssl_scache'
Keeping the relevant 'ssl_scache' in 'data->state' leads to problems
when the owner of the cache is cleaned up and this reference is left
dangling.

Remove the ref entirely and always find the ssl_scache at the current
share or multi.

dangling reference when an easy handle is used with easy_perform first

5ffc73c78e transfer: fix CURLOPT_CURLU override logic
- Change setopt and pretransfer to always reset URL related variables
  for a CURLU handle set CURLOPT_CURLU.

This change is to ensure we are in compliance with the doc which says
CURLU handles must be able to override a URL set via CURLOPT_URL and
that if the contents of the CURLU handle changes between transfers then
the updated contents must be used.

Prior to this change, although subsequent transfers appear to be
performed correctly in those cases, the work URL `data->state.url` was
not updated. CURLINFO_EFFECTIVE_URL returns data->state.url to the user
so it would return the URL from the initial transfer which was the wrong
URL. It's likely there are other cases as well.
