Implement the `--enable-versioned-symbols` feature available in
`./configure` for CMake.
Enable with `-DCURL_LIBCURL_VERSIONED_SYMBOLS=ON`. Customize the version
prefix with `-DCURL_LIBCURL_VERSIONED_SYMBOLS_PREFIX=MYPREFIX_`. By
default the prefix matches what autotools uses.
When enabled, the feature is detected and a warning shown if
unavailable. (E.g. on Apple and Windows, it isn't.)
Included `HIDDEN {};` to match autotools, though I don't know if it's
necessary, useful or making any difference.
Differences from the autotools implementation:
- soversion is dynamic instead of hard-coded.
- omits referencing non-curl symbols.
- allows prefix/flavour override.
- more universal feature detection.
- doesn't rely on the in-repo `lib/libcurl.vers.in` file.
Also:
- add mbedTLS and BearSSL versioned symbol prefix support to autotools.
- enable this option in an old-linux job.

Also:
- fix broken libssh `pkg-config` behaviour on old Linux.
(when found, `LIBSSH_LINK_LIBRARIES` remains undefined.)
- delete manual libssh config from Old Linux CI job,
it's no longer necessary.
Closes#14199
- 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.
Closes#14244
- bump rest of the workflows (windows, macos, distrocheck).
- non-native virtualized envs have 2 CPUs, bump down accordingly.
(for `vmactions/omnios-vm` it's just a guess.)
- bump all to nproc + 1.

To test without c-ares and hit `easy_lock.h` on an old system. Use this
new build step to introduce small variations, and also test libssh2.
Also add workaround to existing job to enable libssh. (CMake's generic
auto-detection doesn't seem to work here.):
```
CMake Warning at CMakeLists.txt:908 (find_package):
Could not find a package configuration file provided by "libssh" with any
of the following names:
libsshConfig.cmake
libssh-config.cmake

- cmake: fix `-pedantic-errors` for old CMake with `CURL_WERROR=ON` set.
`-pedantic-errors` option throws a warning with GCC (all versions) and
makes `check_symbol_exists()` fail in CMake versions older than
v3.23.0 (2022-03-29), when CMake introduced a workaround:
https://gitlab.kitware.com/cmake/cmake/-/issues/13208eeb45401161ab7c3cd28
Follow-up to 3829759bd0#12489
- set `CURL_WERROR=ON` for the `linux-old` job in CI.
Closes#13282
Unity mode is not supported by CMake v3.7.2 used in linux-old, but
enable it anyway for consistency and to kick in automatically once
migrating to a newer old Linux in the future.
Also:
- replace `CMAKE_COMPILE_WARNING_AS_ERROR` with `CURL_WERROR`.
- delete default build option `PICKY_COMPILER=ON`.
Closes#13277
This version still has ELTS support and contains some old versions of
key components like cmake to help prevent us from breaking that support.
Closes#13029
