This is intended to better support ports usage of older clang versions:
* Add _LIBCPP_ENABLE_COMPILER_VERSION_CHECKS block around compiler
version checks, to avoid any warnings about support. This makes some
ports that use -Werror fall over.
* When using clang < 15.0, avoid using a type visibility attribute on
the std namespace, as older versions of clang do not support this.

[libcxx] Re-include <osreldate.h> in __config for FreeBSD
In 0a97720d0197 some changes were made to `__config` for assuming that
`__BYTE_ORDER__` is always present.
However, this deleted a `<osreldate.h>` include for FreeBSD, which is
required to get the value of `__FreeBSD_version`, and that is used later
in the file to determine whether `_LIBCPP_C_HAS_NO_GETS` needs to be
enabled.
Include `<osreldate.h>` just after the other includes used for feature
detection, to fix this.
Note that when FreeBSD 13 is EOLed, this can be removed, as then all
supported FreeBSD versions will no longer have `gets()`.

This is trivial fix of hdacc_detach to avoid duplicated free on snd_hda
unloading.
The first try of detaching (kldunload) may results into "device busy" error,
but codec->fgs is freed by detach. Second try attempts to free codec->fgs again
and system panicks.
Here is example:
pcm0: unregister: channel pcm0:virtual:dsp0.vp0 busy (pid 3428)
pulseaudio[3428] [oss] module-oss.c: DSP shutdown.
pcm0: detached

Also, the "severity" of these events generally only justifies LOG_INFO

It's possible for the capture buffer to be smaller than indicated by the

There is no sense to have separate implementations for FreeBSD and Linux. Make
Linux code shared as more functional and just register FreeBSD-specific prune

Aside of code cleanup this fixes excessive pruning on FreeBSD.

this unused variable can be safely removed.

A nonzero `userrefs` of a linker file indicates that the file, either
loaded from kldload(2) or preloaded, can be unloaded via kldunload(2).
As for the kernel file, it can be unloaded by the loader but should not
be after initialization.
This change fixes regression from d9ce8a41ea which incidentally
increases `userrefs` of the kernel file.

If a string is at or near the end of an input file and the amount of
remaining data in the file is smaller than the maximum string size,
the pread(2) system call would return a short read which is treated as

which permits short reads so long as the data read from the file
contains a terminated string.
