When a multiplex connection (h2/h3) is shutdown by the server, the
reported number of parallel transfers allowed drops to 0.
Determine that when the last transfer is done and terminate the
connection instead of keeping it in the cache.
We detect the drop to 0 also when we try to reuse such a connection, but
if we know this at the time the last transfer is done, we better
terminate it right away.
Have a consistent trace logging to this with the connections current
hostname and port. Adjust test expectations to carry port numbers.

- add 'use warnings' and 'use strict' where missing from Perl scripts.
- fix 'Use of uninitialized value'.
- fix missing declarations.
- test1140.pl: fix 'Possible precedence issue with control flow operator'.
- fix other misc issues.
Most actual errors found during this PR were fixed and merged via
separate PRs.
Likely there are remaining warnings not found and fixed in this PR.
Closes#17877
Collision happens when building with mingw-w64 v3 or v2 while targeting
Vista or newer. `iphlpapi.h` includes `windns.h` in this case, which
defines macros named `DNS_TYPE_*`, colliding with curl doh enums.
The issue was fixed in mingw-w64 v4:

Fixes:
```
lib/doh.h:54:3: error: expected identifier before numeric constant
DNS_TYPE_A = 1,

This workaround seems harmless and generally good practice, but
another option is to require mingw-w64 v4.
Ref: #18009Closes#18041
If the long option name ends with an equals sign (`=`), the argument is
the text following on its right side.
This makes the command line parser accept this common style in addition
to the existing way to accept option arguments more similar to how other
command line tools do.
Example: `curl --user-agent=curl-2000 https://example.com/`
Change a few existing tests to use this syntax: 206, 1333, 1335, 1442
Closes#17789
This still allows users to explictily ask for 1.0 or 1.1 as the minimum
version. If the TLS library allows it.
Starting with this change, the CURL_SSLVERSION_DEFAULT value is no
longer used as minimum version when the TLS backend are called.
This also makes curl set the minimum version to 1.2 independently of
libcurl for the rare case where a newer curl tool would use an older
libcurl.

After 7cf8414fab#12862, `VAR=` no longer
removes the env variable, but sets it to an empty/blank value instead.
To remove an env, `VAR` shall be used (without the assigment operator.)
`SSL_CERT_FILE`, `CURL_HOME`, `HOME`, `XDG_CONFIG_HOME`, were added
before the change above. Make tests unset these envs again, as their
commit messages suggest, instead of blanking them. It does not change
the outcome of the tests.

Slight downside is that this now resets the language/culture to `C`.

Closes#17933
Setting `CURL_ENTROPY` in debug-enabled builds overrides the code paths
responsible for random number generation. To avoid masking issue there,
this patch moves `CURL_ENTROPY` settings to each test that requires it,
and stop setting it by default for all tests (in `runner.pm`).
This makes it possible to catch random generator issues in debug-enabled
builds; extending test coverage.
To keep offering a well-defined state for tests, make `runner.pm` delete
the `CURL_ENTROPY` env, if present.

Fix test 1175 by passing the source root directory (was: tests).
Before this patch this caused silent Perl warnings and returning success
without executing the tests, due to:
```
readline() on closed filehandle $f at ../../tests/test1175.pl line 55.
readline() on closed filehandle $f at ../../tests/test1175.pl line 39.
```
Running the test revealed these issues:
```
CURLE_FUNCTION_NOT_FOUND is not in libcurl-errors.md
CURLE_HTTP_POST_ERROR is not in libcurl-errors.md
CURLE_TELNET_OPTION_SYNTAX is not in libcurl-errors.md
CURLM_CALL_MULTI_SOCKET is not in libcurl-errors.md
```
Apply fixes:
- mark `CURLE_FUNCTION_NOT_FOUND` deprecated by 7.53.0
- mark `CURLE_HTTP_POST_ERROR` deprecated by 7.56.0
- mark `CURLE_TELNET_OPTION_SYNTAX` deprecated by 7.78.0
- document `CURLM_CALL_MULTI_SOCKET` as a synonym for
`CURLM_CALL_MULTI_PERFORM`
- test1477: exclude `CURLM_CALL_MULTI_SOCKET`.
But, these weren't officially deprecated. It may need more updates
to reflect that in other places, or fix the issues differently.

- make `test*` sources include `first.h`, like all others.
- drop redundant `curlx/*` includes after the above.

(and `first.h` had almost no content.)

Closes#17875
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`.
- drop now redundant per-test curlx header includes.
Closes#17868
They were using a macro designed for unit tests. It does not fail when
used in libtests. Make similar macros for these tests, and make them
return a failure.
Also:
- makes these two tests align with the rest of libtests, by including
`first.h` instead of `curlcheck.h`.
- since libtests no longer need to depend on tests/unit, drop this
dependency from build scripts.
Closes#17867
This callback was permanently mapped to libcurl's internal
`Curl_wcsdup()`, which always uses the customizable malloc for
allocation, thus making a custom mapping redundant anyway.
To simplify, drop the callback and map `_tcsdup()` in Unicode mode
directly to `Curl_wcsdup()`.
Also fixes:
- `curl_global_init()` which, before this patch, (re)initialized its
mapping to `_wcsdup()`, returning buffers potentially incompatible
with a custom allocator.

Closes#17843
The idea here is to set limits per test how many allocations and maximum
amount of memory it is allowed to use. This is a means to make sure the
number and total size of allocations are kept in check and don't
mistakenly "blow up".
If runtests.pl detects that the given limits have been exceeded it fails
the test case with an error.
The `<verify>` part now supports `<limits>`, and in this section two
limits can be set for each test (verified in debug builds only):
Allocations: [number of allocation calls]
Maximum allocated: [maximum concurrent memory allocated]
Default limits (used if nothing is set in the test file):
Allocations: 1000
Maximum allocated: 1000000
