Mike Crowe e996fa72a9 nptl: Add POSIX-proposed pthread_rwlock_clockrdlock & pthread_rwlock_clockwrlock
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.

	* sysdeps/unix/sysv/linux/x86_64/x32/libpthread.abilist
	(GLIBC_2.30): Likewise.
	* nptl/tst-abstime.c (th): Add pthread_rwlock_clockrdlock and
	pthread_rwlock_clockwrlock timeout tests to match the existing
	pthread_rwlock_timedrdloock and pthread_rwlock_timedwrlock tests.
	* nptl/tst-rwlock14.c (do_test): Likewise.
	* nptl/tst-rwlock6.c Invent verbose_printf macro, and use for
	ancillary output throughout. (tf): Accept thread_args structure so
	that rwlock, a clockid and function name can be passed to the
	thread. (do_test_clock): Rename from do_test. Accept clockid
	parameter to specify test clock. Use the magic clockid value of
	CLOCK_USE_TIMEDLOCK to indicate that pthread_rwlock_timedrdlock and
	pthread_rwlock_timedwrlock should be tested, otherwise pass the
	specified clockid to pthread_rwlock_clockrdlock and
	pthread_rwlock_clockwrlock. Use xpthread_create and xpthread_join.
	(do_test): Call do_test_clock to test each clockid in turn.
	* nptl/tst-rwlock7.c: Likewise.
	* nptl/tst-rwlock9.c (writer_thread, reader_thread): Accept
	thread_args structure so that the (now int) thread number, the
	clockid and the function name can be passed to the thread.
	(do_test_clock): Renamed from do_test. Pass the necessary
	thread_args when creating the reader and writer threads. Use
	xpthread_create and xpthread_join.
	(do_test): Call do_test_clock to test each clockid in turn.
	* manual/threads.texi: Add documentation for
	pthread_rwlock_clockrdlock and pthread_rwlock_clockwrclock.
