tests/unit: hook up unitprotos to the units-clang-tidy target
To make `ninja units-clang-tidy` target work without manually building
core components first.

Also rename the clang-tidy test target generator macro to align its name
with the built-in `add_custom_target()` function.

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.

tests: make individual test sources compile cleanly
Tidy up headers and includes to ensure all individual test source
compile cleanly (but not link). To allow running clang-tidy (and
possibly other static analyzers) on them. It also improves readability
and allows to verify them locally, without the bundle logic.

clang-tidy ignores #included C files, so it's blind to bundle C files
the include these tests. The current workaround of embedding has
a couple of downsides:. meaningless filenames and line numbers,
missing issues, messing up self header paths. Thus, running it on
individual sources would be beneficial.

Also:
- de-duplicate includes.
- untangle some includes.
- formatting/indentation fixes.
- merge `getpart.h` into `first.h`.

tests/libtest: drop TEST_HANG_TIMEOUT redefinition hack
Before this patch the code relied on re-initializing `TEST_HANG_TIMEOUT`
macro before compiling each test, to allow them each to override it to
a custom value for single tests. Thie required re-including `test.h`
into each test.

After this patch this macro becomes a global, immutable, default. Tests
which want to override it can now use alternate macros that do accept
a custom timeout. The only test currently affected is lib1501.

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.)

warnless: drop parts of the read/write preprocessor hack (Windows)
The `#undef` hack is no longer necessary after changing the redifitions
to not map back to the original symbols.

This makes it unnecessary to repeat the redefinitions after compiling
`warnless.c` itself (in unity mode).

Which in turns makes it unnecessary to include `warnless.h` again, to
trigger such redefinition.

This also means that `read`/`write` are now redefined on Windows from
the first inclusion of `warnless.h`.

Also:
- tests/server: drop a repeat `warnless.h` include, that is unnecessary
  after this patch.
- tests/unit: drop repeat `warnless.h` include.
- tests/libtest: drop repeat `warnless.h` includes.

build: sync tests unity builds between cmake and autotools
Instead of relying on CMake's built-in unity feature, use `mk-unity.pl`,
as already done with autotools. It simplified the build, shortens logs
and makes debugging easier because of the fewer build variations.
It also allows testing / fixing with cmake and those automatically apply
to autotools builds too. cmake builds can be much-much faster, esp.
when working the builds themselves.

It also enables "unity" in old cmake versions. Basically every test
target is a single generated .c source.

Also:
- drop a `lib` unity workaround for libtests with autotools after fixing
  the issue in libtests itself. It drops a few exceptions and makes
  libcurl build faster (in autotools unity).
- fix another `lib` autotools unity issue and drop the workaround for it
  from `mk-unity.pl`. `srcdir` was missing from the header path.
- simplify `mk-unity.pl` command-lines, drop exclusions.

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/unit: drop no-op setup/stop functions.
- 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,

  lib1571, lib1576.

- mk-bundle.pl: stop defining `LIB*` macros. No longer used.

- libtests: drop all `LIB*_C` guards.

- Make these tests branch at runtime, stop building copies:
  - lib585, based on lib500
  - lib565, based on lib510
  - lib529, based on lib525
  - lib527, lib532, based on lib526

libtests: make test 1503,1504,1505 use the 1502 binary
Adjust the differences at runtime instead of build-time, to avoid
extra buillds.

Set the `CURL_TESTNUM` env variable to pass test numbers to tests.

Make libtest/first.c use that env variable to set the `testnum` global
variable to allow tests to differ based on which test that runs it.

tests: drop mk-bundle exceptions
Using a mixture of techniques to avoid symbols collisions:
- reduce scope.
- add `t*_` / `T*_` prefix.
- move shared functions to `testutil.c`.
  (`suburl()`, `rlim2str()`)
- clone re-used lib*.c sources.
  (lib587, lib645)
- include shared symbols just once in re-used `lib*.c` sources.
  (using `LIB*_C` guards.)
- drop re-used `lib*.c` sources where they were identical or
  unused.
- make macros global.
- #undef macros before use.

What remain is the entry functions `test`, and `unit_setup`,
`unit_stop` in unit tests.

Also:
- fix formatting and other minor things along the way.
- add `const` where possible.
- sync some symbol names between tests.
- drop `mk-bundle-hints.sh` that's no longer necessary.

system.h: remove some macros
Since curl_off_t is always 64 bit these days, we can simplify and avoid
using some macros.

ws: tests and fixes
This started out as regression tests for the `curl_ws_recv()` and
`curl_ws_send()` implementation and ended up with a bugfix, additional
protocol validation and minor logging improvements.

- Fix reset of fragmented message decoder state when a PING/PONG is
  received in between message fragments.

- Fix undefined behavior (applying zero offset to null pointer) in
  curl_ws_send() when the given buffer is NULL.

- Detect invalid overlong PING/PONG/CLOSE frames.
- Detect invalid fragmented PING/PONG/CLOSE frames.
- Detect invalid sequences of fragmented frames.

  - a) A continuation frame (0x80...) is received without any ongoing
    fragmented message.
  - 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.

- 2700: Frame types
- 2701: Invalid opcode 0x3
- 2702: Invalid opcode 0xB
- 2703: Invalid reserved bit RSV1 _(replaces 2310)_
- 2704: Invalid reserved bit RSV2
- 2705: Invalid reserved bit RSV3
- 2706: Invalid masked server message
- 2707: Peculiar frame sizes _(part. replaces 2311)_
- 2708: Automatic PONG
- 2709: No automatic PONG _(replaces 2312)_
- 2710: Unsolicited PONG
- 2711: Empty PING/PONG/CLOSE
- 2712: Max sized PING/PONG/CLOSE
- 2713: Invalid oversized PING _(replaces 2307)_
- 2714: Invalid oversized PONG
- 2715: Invalid oversized CLOSE
- 2716: Invalid fragmented PING
- 2717: Invalid fragmented PONG
- 2718: Invalid fragmented CLOSE
- 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.

license: update some copyright links to curl.se
Instead of curl.haxx.se

Also widen the .gitignore for libtest, since it missed libtest751,
so ignore three digit tests that start with 5-9 instead of just 5-6.
