`certdata` dependency requires accessing api.github.com for
a reproducible timestamp, which in turn requires a GitHub token to avoid
errors due to rate limiting. Avoid all this by omitting this dependency,
which isn't necessary for these build tests anyway.
The `zero` job already did not use `certdata`, but disable explicitly
anyway just in case.

libssh 0.12.0 on Windows 64-bit Intel fails to connect to sshd (with SSH
state 30) when using the mlkem768x25519-sha256 KEX. (32-bit Intel, ARM64
and tested non-Windows platforms work fine.) Fix by disabling this KEX
for the libssh job.
I do not recommend libssh on Windows due to bugs an insecure behavior.
Also:
- fix libssh TFLAGS condition for mingw-w64.

Bumping `msys2/setup-msys2` from 2.30.0 to 2.31.0 also brought libssh
0.12.0 (after 0.11.3). libssh has been long known for loading OpenSSH
configuration from disk insecurely on Windows. 0.12.0 brings some fixes
to this (CVE-2025-14821), which in turn may be changing its behavior on
the default GH Windows runner to fail all curl SCP/SFTP tests.
Detecting what is the exact root cause, then defining exact runtime
conditions for it is difficult and fragile. Same for changing these
libssh defaults (if at all possible.)
But, since configuration loading remains insecure and broken on Windows
even after the mitigations made by 0.12.0 [0], this patch removes libssh
from the Windows CI job using it previously.
If someone figures out how to run in CI, it can be readded, though in
general, using libssh on Windows seems to be less than ideal.

It's been going on for almost a year, chances seem slim to have this
fixed upstream.
The observed issue is that on GitHub-supplied CI runner images,
sometimes, `apt-get install` using the stock distro server
`http://azure.archive.ubuntu.com/ubuntu` sees extreme slowness while
downloading data, then reaching the job timeout and aborting, making CI
red and necessitating a manual restart of the failed job(s).
In majority of cases the install step takes no longer than 8-40 seconds
(download + install), while in the failing case it takes 10-20+ minutes
just to download.
Earlier I slimmed down installs to avoid unnecessary packages, which
mitigated, but did not completely fix the issue.

Verify if lines are not longer than 192 characters. Also verify if lines
have less than 79 repeat spaces (and fix one fallout).
To improve readability by avoiding long lines and to prevent adding
overly long lines with text that may go unnoticed in an editor or diff
viewer.
In addition to pre-existing line length limits: 79 for C, 132 for CMake
sources.
Also:
- spacecheck: fix/harden allowlist regexes.
- spacecheck: tidy-up quotes and simplify escaping.
- spacecheck: allow folding strings with repeat spaces.
- GHA: fix a suppressed shellcheck warning.
- GHA/macos: simplify by dropping brew bundle.
- test1119.pl: precompile a regex.
- FAQ.md: delete very long link to a Windows 7/2008 support article
that's lost it relevance.

c-ares builds have been sped up within curl-for-win using, pre-fills. It
allows building it with acceptable performance, making it practical to
use it, alongside HTTPS-RR, in curl CI and possibly in curl-for-win. It
has been enabled in its dev branch for a while.

After limiting `find_package()`/`find_dependency()` calls to curl local
Find modules via the `MODULES` keyword, it became possible to detect
dependencies via CMake Configs from within those local Find modules, by
calling `find_package()` again with the `CONFIG` keyword. This patch
implements this. Then maps detection results to the result variables and
curl-specific imported targets the rest of the build expects.
Also honor recently introduced `*_USE_STATIC_LIBS` (experimental) flags
to map to the static target when requested.
This adds CMake Configs as an alternative to the existing `pkg-config`
and `find_path()`/`find_library()` auto-detection methods.
Enabled by default for MSVC, outside vcpkg and when not cross-building.
To enable for other cases, or override the default, you can use
`-DCURL_USE_CMAKECONFIG=ON` or `OFF`.
When enabled, Config detection happens after `pkg-config` and before
`find_path()`/`find_library()`. Using CMake's built-in options, you may
also manually point to the absolute directory holding Config files:
`Libssh2_DIR`, `MbedTLS_DIR`, `NGHTTP2_DIR`, `NGHTTP3_DIR`,
`NGTCP2_DIR` v1.19.0+ (with non-fork OpenSSL only), `Zstd_DIR` v1.4.5+
E.g. `-DMbedTLS_DIR=/path/to/mbedtls/lib/cmake/MbedTLS`
These dependencies typically need to be built with CMake to support
this.
Tagged as experimental.
