tool_parsecfg: detect and error on recursive --config use
The config file parser now has a maximum level of inclusions allowed (5)
to detect and prevent recursive inclusions of itself leading to badness.

Bonus: clean up return code handling from the config parser.

curl_path: make sure just whitespace is illegal
This function could previously accidentally return true and a NULL path
if only whitespace was provided as argument.

Also, make it stricter and do not allow CR or LF within the string.

tool_formparse: rewrite the headers file parser
The -F option allows users to provide a file with a set of headers for a
specific formpost section. This code used old handcrafted parsing logic
that potentially could do wrong.

Rewrite to use my_get_line() and dynbuf. Supports longer lines and
should be more solid parsing code.

Gets somewhat complicated by the (unwise) feature that allows "folding"
of header lines in the file: if a line starts with a space it should be
appended to the previous.

The previous code trimmed spurious CR characters wherever they would
occur in a line but this version does not. It does not seem like
something we want or that users would expect.

Test 646 uses this feature.

test_16: adjust timing expectations
In MOST protocols and runs, the 'pretransfer' time is less than the
'starttransfer'. E.g. request being sent before response comes in.

However, when curl is starved of cpu a server response might start
streaming in before the multi-state transitioned to DID (and recorded
the 'pretransfer' time).

Do no longer check that 'pretransfer' is less or equal 'starttransfer'.
Check that is is less or equal to the total time instead.

mbedtls: add support for 4.0.0
After this patch libcurl requires (as already documented)
the `curl_global_init()` call when using the `curl_formadd()` API with
mbedTLS.

Note: NTLM is not supported with mbedTLS 4+, because it lacks
the necessary crypto primitive: DES.

Also:
- lib: de-dupe mbedTLS minimum version checks into `curl_setup.h`.
- lib: initialize PSA Crypto as part of `curl_global_init()`.
  For MD5, SHA-256, `curl_formadd()`, and MultiSSL builds with mbedTLS
  but where mbedTLS isn't the default backend.
- lib1308: fix to call `curl_global_init()` (for the Form API).
- curl_ntlm_core: disable with mbedTLS 4+.
- md4: disable mbedTLS implementation when building against 4.x.
- md5: use mbedTLS PSA Crypto API when available, otherwise use
  the default local implementation.
- sha256: use mbedTLS PSA Crypto API when available, otherwise use
  the default local implementation.
- vtls/mbedtls: drop PSA Crypto initialization in favor of
  `curl_global_init()`.
- vtls/mbedtls: use PSA Crypto random API with all mbedTLS versions.
- vtls/mbedtls: do the same for the SHA-256 callback.
- autotools: detect mbedTLS 4+, and disable NTLM for 3.x.
- cmake: disable NTLM for mbedTLS 3.x.
- GHA/linux: keep building mbedTLS 3.x manually and use it in
  an existing job, while also enabling pytest in it.
- GHA/linux: bump to mbedTLS 4.0.0.

e7247d8697 tool_operate: keep failed partial download for retry auto-resume
- Keep data from a failed download instead of discarding it on retry in
  some limited cases when we know it's ok (currently only HTTP 200/206).

Prior to this change on failed transfer the tool truncated any outfile
data written before retrying the transfer. This change adds an exception
for HTTP downloads when the user requested auto-resume, because in that
case we can keep the outfile data and resume from the new position.

tests/server: drop pointless memory allocation overrides
The code was overriding system memory allocation functions to a local

tests: stop overriding system printf symbols
To make the source code match the functions called at runtime.
And to avoid the preprocessor trick that may introduces build issues.

Before this patch, libtests, tunits and units were calling a mixture
of curl and system printf calls, then transformed them all to curl
printf calls by including `curl_printf.h`.

Changes made:
- tests: stop including `curl_printf.h`.
- libtest: switch a couple of outlier system printf calls to curl
  printf.
- unit: use more curl printf to avoid casts and show whole values.
- unit: switch remaining calls to curl printf explicitly.
- tunit: switch to call curl printf explicitly.
- libtest, tunit, unit: ban system printf.
- unit1307, unit1607, unit1609, unit1652, unit1655, unit3214: bump
  types/masks to avoid casts.

After this patch:
- libtests, tunits, units: use exclusively curl printf.
  (as before, but explicitly, without relying on redefinitions.)
- servers: is unchanged (it can only use system printf).

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

tests/server: drop unsafe open() override in signal handler (Windows)
Turns out the signal handler on Windows still wasn't signal safe after
the previous round of fix. There is an `open()` call made from there,
and `open` happens to be unconditionally overridden via `curl_setup.h`
on Windows, to its local implementation (`curlx_win32_open()`), which
does memory allocations and potentially other things that are not signal
safe.

This is a temporary fix, till avoiding the override of system symbols
`open` and `stat` on Windows.

FTR this did not fix the CI 2304 errors, diskspace fail or job hangs due
to 0xC0000142 fork failure (it's rare all three occurs in the same run):

perlcheck: add script, run in CI, fix fallouts
Add script to run all Perl sources through `perl -c` to ensure no
issues, and run this script via GHA/checksrc in CI.

Fallouts:
- fix two repeated declarations.
- move `shell_quote()` from `testutil.pm` to `pathhelp.pm`, to
  avoid circular dependency in `globalconfig.pm`.
