tests: speed up builds with single-binary test bundles

Add support for single-block binaries that contain all libtests and
unit tests respectively.

Enable with:
- autotools: `--enable-test-bundles`
- cmake: `-DCURL_TEST_BUNDLES=ON`

(They are compatible with `--enable-unity` and `-DCMAKE_UNITY_BUILD=ON`
options, for further speed-up.)

Makes libtests and unit tests build _fast_, needing little disk space
even in static mode. Similar to CMake unity mode, but with a custom
script, also supporting autotools builds.

The price is having to deal with symbols/macros colliding between
`lib*.c` and `unit*.c` sources. Maybe with naming conventions or other
solutions this can be improved gradually and reduce the need for manual
intervention by `mk-bundle.mk`. I've included a script that does the bulk
of detecting name collisions.

Also:
- CI: enable test bundles.
- CI: build tests in more jobs.
- lib2305: fix FILE handle leak.
- unit1661: fix memleak found by torture test by releasing the `bufref`
structure in `unit_stop()` that was allocated in `unit_setup()`.
```
test 1661...[bufref unit tests]
Leak detected: memory still allocated: 13 bytes
allocated by /home/runner/work/curl/curl/tests/unit/unit1661.c:70
1661: torture FAILED: function number 1 in test.

autotools: add support for 'unity' builds, enable in CI

Implement the "unity" builds as known from CMake, but for autotools.
It's limited to `lib` and `src` (CMake also supports it in `tests`).

Enable with: `--enable-unity` (disabled by default)

Unity builds speed up builds significantly. Cygwin and Windows builds in
particular, but the effect is noticeable on most systems. It also allows
discovering unity issues with autotools, benefitting also CMake when
building the same combination. In CI it makes turnaround times quicker.

This closes build performance with CMake. autotools still lags behind
because it builds shared and static libcurl in two, separate passes.
CMake does it in one. Manpage compilation isn't batched, it is in CMake.
After unity and test bundle support the slowest parts of the build are
the configuration phase (which is effectively a tedious, non-parallel,
compilation and/or linking of 300+ tiny programs. The next bottleneck
is compiling individual examples and finally test servers (only slow
with autotools).

The autotools implementation is slightly less efficient than CMake,
because 3 sources are permanently excluded while in CMake this isn't
necessary and solved more efficiently while building libtests. There is
also no 'unity' support for tests, making them a less efficient also.

Enable it in CI for most `configure` jobs. Except in GHA/dist (though
it works fine there too), to use the default config there. Also skip for
the Linux AWC-LC job where it made builds time a few seconds longer
(reason undiscovered.)

cmake: separate target for examples, optimize CI, fix fallouts

- Move `docs/examples` builds under a separate target.

- Make `BUILD_EXAMPLES` default to `ON`. It means to generate the rules
for `docs/examples` by default, but not build them. To build them,
an explicit `make curl-examples` (or ninja, etc) command is necessary.
This syncs behaviour with autotools, and also how both cmake and
autotools are building tests.

- GHA: update cmake jobs to use the new way of building examples.

- GHA: move examples build step at the end of the job, after building
and running tests. This allows to have build and test run results
faster, and leave the seldom-changing examples build to the end.
Building examples is the slowest build step with no practical way to
make them fast.

- appveyor: enable building examples in two old-MSVC jobs.

- examples: fix examples to build cleanly with old MSVC versions.

- GHA/non-native: move example build log under a GHA foldable section.

- GHA/windows: move building examples into separate step for Linux cross
jobs.

- NetBSD: enable impacket. Debatable if this hefty package is worth it
for the single SMB test (1451) run curl uses it for.
(on the upside, it seems to install instantly on NetBSD)
It's also a versioned package name that requires active maintenance.
The unversioned name doesn't work, though that's what the package
search returns: https://pkgsrc.se/net/py-impacket

They are automatically installed via the impacket package.

- GHA/windows: ignore failing 1451 'Basic SMB request' test for
old mingw-w64 7.3.0 (but not for 9.5.0!):
```
2024-09-11 21:45:59,738 ERROR smbComNegotiate: b'NT LM 0.12\x00' is not in list

curl: (7) Could not connect to server

```
Ref: https://github.com/curl/curl/actions/runs/10816280746/job/30007130770#step:13:3546
- CI/Azure: delete, now moved to GHA.

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 `sshd_config`:
```
D:/a/curl/curl/bld/tests/log/2/server/curl_sshd_config line 7: Deprecated option AuthorizedKeysFile2
D:/a/curl/curl/bld/tests/log/2/server/curl_sshd_config line 25: Deprecated option KeyRegenerationInterval
D:/a/curl/curl/bld/tests/log/2/server/curl_sshd_config line 35: Deprecated option RhostsRSAAuthentication
D:/a/curl/curl/bld/tests/log/2/server/curl_sshd_config line 36: Deprecated option RSAAuthentication

D:/a/curl/curl/bld/tests/log/2/server/curl_sshd_config line 41: Deprecated option UseLogin
```
- 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.
