As BIND 9.20 does not support RHEL/CentOS 7 which just reach
end-of-life, we can safely bump the OpenSSL requirements to version
1.1.1, which in turn will allow us to simplify our OpenSSL integration.
Support for FreeBSD 12.4, the last FreeBSD 12.x release, ended on
December 31, 2023.

Move the --with-readline=editline ./configure option to FreeBSD 14.
The system tests on OpenBSD consistently exhibit lower stability
compared to our other CI platforms. Some of these challenges are
intrinsic to the system test itself and require attention. However,
there are OpenBSD issues, which seem to be more widespread on this
platform than others. In our daily CI pipelines, OpenBSD system tests
often bear the brunt of all failed CI jobs.
It's possible that our OpenBSD CI image could be optimized, but we
currently lack the domain-specific knowledge needed to make
improvements.
Move i386 and other less common or ancient CPU architectures to
Community-Maintened category. Move armhf and arm64 to the Best-Effort
category as we do test them as part of development work (new MacBooks
are all arm64), we don't really do full set of tests in the CI.
The RHEL (and clones) 7 will reach EOL in June 2024, shortly after BIND
9.20 will be released. Drop the support for building on those
platforms, so we can use features of modern operating systems - newer
compiler that supports at least subset of C23 and OpenSSL 1.1/3.0.
This will simplify some of the code that we are using in BIND 9.
By bumping the minimum libuv version to 1.34.0, it allows us to remove
all libuv shims we ever had and makes the code much cleaner. The
up-to-date libuv is available in all distributions supported by BIND
9.19+ either natively or as a backport.
We have had perpetual problem with Sphinx implicitly double-including
files. To avoid that problem all files with name suffix .inc.rst are now
ignored by Sphinx, and writter can conveniently include them without
modifying conf.py for each and every file.
