C23 has incoporated a small number of POSIX functions, so these
should be exposed for C23, regardless of POSIX.

time.h: reduce CLOCK_ namespace pollution, move to _clock_id.h2021-07-30T23:20:22ZWarner Loshimp@FreeBSD.org2021-07-30T23:10:56Zurn:sha1:7b797ba27a714594dac910035d857e653d566b19
Attempt to comply with the strict namespace pollution requirements of
_POSIX_C_SOURCE. Add guards to limit visitbility of CLOCK_ and TIMER_
defines as appropriate. Only define the CLOCK_ variables relevant to the
specific standards. Move all the sharing to sys/_clock_id.h and make
time.h and sys/time.h both include that rather than copy due to the
now large number of clocks and compat defines.
Please note: The old time.h previously used these newer dates:
CLOCK_REALTIME 199506
CLOCK_MONOTONIC 200112
CLOCK_THREAD_CPUTIME_ID 200112
CLOCK_PROCESS_CPUTIME_ID 200112
but glibc defines all of these for 199309. glibc uses this date for all
these values, however, only CLOCK_REALTIME was in IEEE 1003.1b. Add a
comment about this to document it. A large number of programs and
libraries assume that these will be defined for _POSIX_C_SOURCE =
199309.
In addition, leak CLOCK_UPTIME_FAST for the pocl package until it can be
updated to use a simple CLOCK_MONOTONIC.

Correctly check for C++17 and higher when declaring timespec_get()2019-12-09T19:17:56ZDimitry Andricdim@FreeBSD.org2019-12-09T19:17:56Zurn:sha1:bc053cafcaa284323172c45995fff6d26b9189ab
Summary:
In rS338751, the check to declare `timespec_get()` for C++17 and higher
was incorrectly done against a `cplusplus` define, while it should have
been `__cplusplus`.
Fix this by using `__cplusplus`, and also bump `__FreeBSD_version` so it
becomes possible to correctly check for `timespec_get()` in upstream
libc++ headers.

Bring in timespce_get form NetBSD.2018-08-10T15:16:30ZWarner Loshimp@FreeBSD.org2018-08-10T15:16:30Zurn:sha1:7e299411ac91383d8a28de9fadd2b4ed8a148fff
Bring in the functionality for timespec_get from NetBSD. I've lightly
edited the .c file to remove _DIAGASSERT because FreeBSD doesn't have
that functionality and the typical #define'ing it to assert isn't
right here. The man page is verbatim from NetBSD, but will be revised
as part of a larger cleanup of the time man pages (they are
inconsistent and vague in all the wrong places).
