GHA: move Cygwin jobs back into the Windows workflow

Cygwin jobs took 30 minutes and was the reason for moving them to their
own workflow. After recent changes, they finish in 8 minutes, which is
on par or lower than the longest Windows jobs. Thus, Cygwin can now be
moved back to the Windows workflow without causing extra wait for all
the workflow jobs to complete (and allowing a manual retry for the
remaining flaky jobs).

Notice that Cygwin still uses the cygwin/cygwin-install-action action to
install Cygwin itself. This action uses no caching and the time it takes
fluctuates widely depending on mirror speed, congestion and other
things. If Cygwin tends to hold up jobs again for this or other reasons,
this patch may be reverted.

CI: move Azure jobs to GHA, fix fallouts, sshserver, runtests tweaks

CI:

Skip `impacket` on MSYS2 due to install failure.
Skip OpenSSH server for old/standalone mingw-w64 (building curl
without SSH there.)
- GHA/windows: make test tool installs a separate step.
- GHA/cygwin: enable OpenSSH server.
Skip `impacket`: it's compiling for 7 minutes then breaks.
Skip `stunnel` due to sluggish test run performance.
(This update is unrelated to Azure jobs.)
- GHA/linux: migrate Linux jobs from Azure CI.
- GHA/linux: migrate scanbuild job from Azure CI.
- GHA/linux: enable libssh2 in a job. Also enable valgrind.
- CI/windows: enable SSPI in two jobs.
- CI/windows: disable zlib in one more job.
- CI/windows: improve `if` condition checking GnuTLS.
- CI/windows: ignore SFTP/SCP tests as necessary.
- universally ignore SCP tests, they fail everywhere.
- ignore test 612.
- ignore test 613 616 618 with MSYS2 mingw-w64.
- ignore test 614 with libssh.
- ignore all SFTP with MSYS2 native.
- ignore all SFTP with vcpkg with `libssh2[core,zlib]`.
- ignore a couple of SFTP tests with MSYS2 mingw-w64.
(This matches settings on Azure CI.)
- GHA/windows: ignore failing 1451 'Basic SMB request' test for
old mingw-w64 7.3.0 (but not for 9.5.0!):

sshserver:

- sshserver: fix permissions for SSH host key on Windows, allowing sshd
to launch.
- sshserver: fix initializing config paths with Cygwin/MSYS2 sshd.
- sshserver: fix initializing config paths in parallel builds.
- sshserver: delete redundant `DenyUsers`. This also opens the way
to allow multiple usernames.
- sshserver: fix `AllowUsers` for GHA/windows, by allowing the
domainless username again.

```
- sshserver: fix `Deprecated option` warnings in `ssh_config` with
Cygwin/MSYS2.
- sshserver: fix dumping config files due to the filenames missing their
full paths.
- sshserver: add workaround to make `logmsg` messages visible.
Before this patch they only went to a file and never shown.

runtests:

- runtests: log details when these Windows commands are called:
`handle`, `taskkill`, `tasklist`.
- runtests: add documentation links to Windows tools:
`handle`, `taskkill`, `tasklist`, `icacls`.
- runtests: add `-t` (kill whole tree) option to `taskkill` in
`servers.pm`, syncing it with the other `taskkill` call.
Follow-up to bc72a78a11764558639131d51fa8e7c81ee1e113 #14488
- runtests: show warning if Sysinternals `handle` tool is missing.
- runtests: drop Windows XP Home compatibility `tskill` call.
The call was made on all Windows versions. It's possibly overkill to
do this, because XP Home is probably rarely used for running curl
tests these days. In case it's needed, it'd be better to put it under
an explicit option.
- runtests: show Perl version and path.

Fix/silence fallouts:

- unit2603: fix building with disabled HTTP support.
- unit2604: silence `-Woverlength-strings` warnings in C89 mode.
- test437, test1614: fix to pass with no-IPv6 builds.

CI: consolidate workflows for source and docs check

A bunch of tiny jobs that run various source or documentation checks are
consolidated into two workflow files: checksrc.yml and checkdocs.yml.
This reduces the proliferation of new files containing one-line checks
and brings those that operate similarly together for better reasoning
about them. The man-examples check is also now running again for the
first time in 7 months.

Various calls to find, xargs and git ls-files are changed where possible
to use NUL line terminators in pipes to avoid issues with oddly-named
files that might find their way into the repo.

Our convention for naming Find modules (the part after the `Find`
prefix, also called as 'package name') is:

Always start with uppercase. Follow with lowercase, unless there is
a clear preference for a stylized name. E.g. the project itself uses it
that way with a matching `<Name>Config.cmake` file, or we use it that
way elsewhere, or the name is an acronym.

GHA/windows: move Cygwin into its own workflow

Cygwin runs stable but slow, while native Windows in the same workflow
runs fast but unreliable (hangs). GHA requires all jobs to finish before
allowing to re-run failed ones. Before this patch this meant waiting for
the slow Cygwin jobs to re-run hung native jobs. After this patch Cygwin
jobs run in their own workflow, allowing to re-run broken Windows jobs
earlier.

GHA/non-native: improve, migrate x86_64 FreeBSD with tests from Cirrus CI

GHA/non-native: improve, migrate x86_64 FreeBSD with tests from Cirrus CI

- run tests via `make test-ci` instead of `make check` with autotools.
- add `x86_64` job for FreeBSD, with tests.
It matches the existing Cirrus CI job, with these differences:
- finishes 3x faster (thanks to parallel tests enabled).
- librtmp is not enabled because it's slated for removal by FreeBSD.
(already past the removal deadline, thought the package still
installs.)
- DICT and TELNET servers fail to start. Couldn't figure out why.
It means skipping test 1450 and 1452.
- it runs more tests, e.g. websockets and ip6-localhost.
- no `pkg update -f`.
- it misses the `CRYPTOGRAPHY_DONT_BUILD_RUST=1`, `pkg delete curl`,
`chmod 777`, `sudo -u nobody` and `sysctl net.inet.tcp.blackhole`
tricks. The latter is the default in these runners, the others did
not affect results.
- set `-j0` for tests in the NetBSD job. Flaky otherwise.

GHA: add MSYS, mingw-w64, Cygwin jobs

- re-implement autotools MSYS and Cygwin AppVeyor jobs in GHA.
Now build with SSL and PSL to improve test coverage.
- re-implement MSYS2 mingw-w64 gcc 13 AppVeyor job in GHA.
`CMake, mingw-w64, gcc 13, Debug, x64, Schannel, Static, Unicode`
- add new cmake Cygwin job (build-only).
- enable `-j14` parallelism when running tests.
- delete the 5 migrated jobs from AppVeyor CI.
- add 2 build-only mingw-w64 builds, gcc Release and clang OpenSSL.
- also enable brotli, libssh2, nghttp2 for more test coverage.

These jobs offer better performance, more flexibility and
parallelization compared to the AppVeyor ones they replace. It also
offloads AppVeyor, allowing to iterate faster. They also appear more
reliable than e.g. Azure Windows jobs, where runners are prone to fail
[1].

appveyor: replace PowerShell with bash + parallel autotools

PowerShell works (after a steep development curve), but one property of
it stuck and kept causing unresolvable usability issues: With
`$ErrorActionPreference=Stop`, it does abort on failures, but shows only
the first line of the error message. In `Continue` mode, it shows the
full error message, but doesn't stop on all errors. Another issue is
PowerShell considering any stderr output as if the command failed (this
has been improved in 7.2 (2021-Nov), but fixed versions aren't running
in CI and will not be for a long time in all test images.)

Thus, we're going with bash.

Also:
- use `-j2` with autotools tests, making them finish 5-15 minutes per
job faster.
- omit `POSIX_PATH_PREFIX`.
- use `WINDIR`.
- prefer forward slashes.
