cdefs.h: Document the _XOPEN_SOURCE - 0 construct
Various System V Interface Definition editions, as well as the X/Open
group portability guide issue 4, recommend defining _XOPEN_SOURCE and
broadly intimating it means the same thing as _POSIX_SOURCE == 2.
Starting in X/Open issue 5 (1995), _XOPEN_SOURCE needs to be defined to
be 500 to bring in the newer interfaces. However, it is still common hat
sources define _XOPEN_SOURCE to be blank. To deal with that, we subtract
0 from _XOPEN_SOURCE to make the other expressions well formed.
While here, document that we should define _POSIX_C_SOURCE to be 199209
based on the SVID, the first version of the Single Unix Specification,
and X/Open CAE issue 4, version 2. Also document that historically this
has been a NOP. Any value of _XOPEN_SOURCE < 500 (including it being
blank) was not viewed as a request for a restricted namespace.

cdefs: Support _ISOC23_SOURCE and --std=c23
If either _ISOC23_SOURCE is defined or --std=c23 (or higher) is
specified, then default to the making the ISO C visibility to 2023.
This mirrors what glibc does, so update the comment for this change to
_ISOCxx_SOURCE values. We currently implement xx = 11 or 23. C17 added
no new defines or symbols, so we follow glibc's lead and ommit it.
However, we don't implement the C95, C99 or C2y versions. These are
non-standard and the first two don't seem to be relevant, and the latter
is also experimental.

Allow applications to request a strict POSIX 2024 by setting

ena.4: optimize apropos and hardware
Remove "FreeBSD kernel driver for" and "family", and
add "AWS EC2" and "driver" to the document description
for better search discoveribility and consistency with
other driver manuals.
Rewrite the introductory sentance to the HARDWARE section
with driver name for inclusion in hardware release notes.

release: Exclude container images from globs
We use a *.txz glob to get all of the "distributions" which comprise
the FreeBSD release, but we now (optionally) also build container
images which are .txz files. Grep those out from the distribution
lists.
A better long-term fix would probably be to generate an explicit list
of the .txz files we want rather than using an overbroad glob and
filtering out the files we *don't* want.

bsd.subdir.mk: Drop broken optimisation for realinstall parallelisation
Not all of the tree is happy for realinstall to be done in parallel. In
particular, Makefile.inc1 uses .WAIT to force etc to be installed after
earlier subdirectories, since etc calls into share/man's makedb to run
makewhatis on the tree and needs all manpages to have been installed.
Also, libexec/Makefile doesn't set SUBDIR_PARALLEL, and the link from
ld-elf32.1 to ld-elf.1 relies on rtld-elf having been installed before
rtld-elf32, otherwise creating the link will fail.
In general, core behavioural differences like this between NO_ROOT and
"normal" builds are also dangerous and confusing.
If this optimisation is deemed important, it should be reintroduced in a
more limited and robust manner that doesn't break the above situations.
Until then value correctness over slight efficiency gains on high core
count machines, the same machines where you're more likely to encounter
issues from this optimisation.

Improve reliability of stdout tests.
If the test runner is under heavy load, the command we are testing may
succeed in printing to stdout before the dummy receiver has terminated.
Add a short delay to reduce the likelihood of this happening.
