1ee349f986 systemclock: Don't keep the clock entry locked while getting the time from the clock
gst_clock_get_time() will take the clock mutex, which would then result in a lock
order violation and possible deadlocks. If both mutexes are to be locked, the
clock must always be locked first.

ec698179a9 systemclock: Get rid of conditional unlocking of the clock entries
At every point it is known whether the entry needs to be unlocked or not.

37b9bfdd2e systemclock: Use a flag while waiting for the async thread to start
Otherwise there can be spurious wakeups.

0e3e688bed systemclock: fix usage of __STDC_NO_ATOMICS__
__STDC_NO_ATOMICS doesn't seem to exist. In fact the only compiler
I've found that sets any of those is msvc, but it sets
__STDC_NO_ATOMICS__, not __STDC_NO_ATOMICS.

__STDC_NO_ATOMICS__ is the one documented by C11 standard.

6ce27e328d gst: clock: Block futex_time64 usage on Android API level < 30
This syscall is seccomp blocked on all lower API levels:

ee7bc3002d

While at it, also fix all direct tests on __NR_futex_time64 and
__NR_futex so that they refer to the results available in
config.h.

c52212604e gst: clock: Clean up code to get the monotonic / realtime clock a bit
On Windows and macOS always use the proper monotonic clock, including
for gst_util_get_timestamp(), and initialize its state only once.

Also on macOS use clock_gettime() for the realtime clock, if available
instead of always falling back to GLib.
