nptl: Add POSIX-proposed pthread_rwlock_clockrdlock & pthread_rwlock_clockwrlock

Browse source 
Add:
 int pthread_rwlock_clockrdlock (pthread_rwlock_t *rwlock,
                                 clockid_t clockid,
                                 const struct timespec *abstime)
and:
 int pthread_rwlock_clockwrlock (pthread_rwlock_t *rwlock,
                                 clockid_t clockid,
                                 const struct timespec *abstime)

which behave like pthread_rwlock_timedrdlock and
pthread_rwlock_timedwrlock respectively, except they always measure
abstime against the supplied clockid. The functions currently support
CLOCK_REALTIME and CLOCK_MONOTONIC and return EINVAL if any other
clock is specified.

	* sysdeps/nptl/pthread.h: Add pthread_rwlock_clockrdlock and
	pthread_wrlock_clockwrlock.
	* nptl/Makefile: Build pthread_rwlock_clockrdlock.c and
	pthread_rwlock_clockwrlock.c.
	* nptl/pthread_rwlock_clockrdlock.c: Implement
	pthread_rwlock_clockrdlock.
	* nptl/pthread_rwlock_clockwrlock.c: Implement
	pthread_rwlock_clockwrlock.
	* nptl/pthread_rwlock_common.c (__pthread_rwlock_rdlock_full): Add
	clockid parameter and verify that it indicates a supported clock on
	entry so that we fail even if it doesn't end up being used. Pass
	that clock on to futex_abstimed_wait when necessary.
	(__pthread_rwlock_wrlock_full): Likewise.
	* nptl/pthread_rwlock_rdlock.c: (__pthread_rwlock_rdlock): Pass
	CLOCK_REALTIME to __pthread_rwlock_rdlock_full even though it won't
	be used because there's no timeout.
	* nptl/pthread_rwlock_wrlock.c (__pthread_rwlock_wrlock): Pass
	CLOCK_REALTIME to __pthread_rwlock_wrlock_full even though it won't
	be used because there is no timeout.
	* nptl/pthread_rwlock_timedrdlock.c (pthread_rwlock_timedrdlock):
	Pass CLOCK_REALTIME to __pthread_rwlock_rdlock_full since abstime
	uses that clock.
	* nptl/pthread_rwlock_timedwrlock.c (pthread_rwlock_timedwrlock):
	Pass CLOCK_REALTIME to __pthread_rwlock_wrlock_full since abstime
	uses that clock.
