nptl: Consolidate pthread_{timed,try}join{_np}
This patch consolidates the pthread_join and gnu extensions to avoid
code duplication.  The function pthread_join, pthread_tryjoin_np, and
pthread_timedjoin_np are now based on pthread_timedjoin_ex.

It also fixes some inconsistencies on ESRCH, EINVAL, EDEADLK handling
(where each implementation differs from each other) and also on
clenup handler (which now always use a CAS).

Checked on i686-linux-gnu and x86_64-linux-gnu.

	* nptl/pthreadP.h (__pthread_timedjoin_np): Define.
	* nptl/pthread_join.c (pthread_join): Use __pthread_timedjoin_np.
	* nptl/pthread_tryjoin.c (pthread_tryjoin): Likewise.
	* nptl/pthread_timedjoin.c (cleanup): Use CAS on argument setting.
	(pthread_timedjoin_np): Define internal symbol and common code from
	pthread_join.
	* sysdeps/unix/sysv/linux/i386/lowlevellock.h (__lll_timedwait_tid):
	Remove superflous checks.
	* sysdeps/unix/sysv/linux/x86_64/lowlevellock.h (__lll_timedwait_tid):
	Likewise.
