nptl: Add POSIX-proposed sem_clockwait
Add:
int sem_clockwait (sem_t *sem, clockid_t clock, const struct timespec
*abstime)
which behaves just like sem_timedwait, but measures abstime against the
specified clock. Currently supports CLOCK_REALTIME and CLOCK_MONOTONIC
and sets errno == EINVAL if any other clock is specified.
* nptl/sem_waitcommon.c (do_futex_wait, __new_sem_wait_slow): Add
clockid parameters to indicate the clock which abstime should be
measured against.
* nptl/sem_timedwait.c (sem_timedwait), nptl/sem_wait.c
(__new_sem_wait): Pass CLOCK_REALTIME as clockid to
__new_sem_wait_slow.
* nptl/sem_clockwait.c: New file to implement sem_clockwait based
on sem_timedwait.c.
* nptl/Makefile: Add sem_clockwait.c source file. Add CFLAGS for
sem_clockwait.c to match those used for sem_timedwait.c.
* sysdeps/pthread/semaphore.h: Add sem_clockwait.
