Drop `strcasecompare` and `strncasecompare` in favor of libcurl API
calls `curl_strequal` and `curl_strnequal` respectively.
Also drop unnecessary `strcase.h` includes. Include `curl/curl.h`
instead where it wasn't included before.
Closes#17772
- tests/libtest: move exception to `stub_gssapi.h`.
- tests/libtest: move remaining exception to `testtrace.c`.
- tests/server: drop obsolete exception.
- docs/examples: move `BANNEDFUNC` exceptions to local files (3 lines).
- docs/examples: move `ERRNOVAR` exception to `ephiperfifo.c`.
- docs/examples: drop `typedef struct` (8 files).
- lib/curlx: add `.checksrc` with banned funcs copied from lib.
- checksrc: ban `strncpy`, `strtok_r`, `strtoul` by default.
Drop local bans. Add exception for `strtoul` to `tests/server'.
- lib, src: sync banned funcs.
Also:
- REUSE: drop `stunnel.pem`, it no longer exists.
- docs/examples: formatting.
- docs/examples: simplify some `sizeof()`s.
Closes#17764
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.
- tests/libtest: formatting.

Use it from libtests' `first.c` and thus also from units, and tunits.
Also:
- cmake: drop stray `curltool` lib dependency for units.
- units: stop depending on `src` headers.
- tests/server: drop depending on `src` headers.
(the remaining one listed in the comments, `tool_xattr.h`, was not
actually used from servers.)
- tests/server: drop duplicate curlx headers.
(Except `warnless.h`, which is tricky on Windows.)
Closes#17672
Both are available with well-known conditions, under non-Windows, and
`curl/curl.h` already uses them. `sys/time.h` is also necessary for
mingw-w64 for `gettimeofday()`.

With a dash, using two Ls. Also for different forms of the word.
Use NULL in all uppercase if it means a zero pointer.

Further untangle the test server code from curl code. While the string
comparison functions are available in the libcurl API, the tests servers
don't link with libcurl. Use native functions instead.
Closes#17328
Drop the interim macro `PRESERVE_WINDOWS_ERROR_CODE` and always preserve
error code for `_WIN32`. To make sure this is always done in
`curlx_winapi_strerror()`.

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.
