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.
