* allocatestack.c (allocate_stack): Always initialize robust_head.
* descr.h: Define struct robust_list_head.
(struct pthread): Use robust_list_head in robust mutex list definition.
Adjust ENQUEUE_MUTEX and DEQUEUE_MUTEX.
* init.c [!__ASSUME_SET_ROBUST_LIST] (__set_robust_list_avail): Define.
(__pthread_initialize_minimal_internal): Register robust_list with
the kernel.
* pthreadP.h: Remove PRIVATE_ from PTHREAD_MUTEX_ROBUST_* names.
Declare __set_robust_list_avail.
* pthread_create.c (start_thread): Register robust_list of new thread.
[!__ASSUME_SET_ROBUST_LIST]: If robust_list is not empty wake up
waiters.
* pthread_mutex_destroy.c: For robust mutexes don't look at the
number of users, it's unreliable.
* pthread_mutex_init.c: Allow use of pshared robust mutexes if
set_robust_list syscall is available.
* pthread_mutex_consistent.c: Adjust for PTHREAD_MUTEX_ROBUST_* rename.
* pthread_mutex_lock.c: Simplify robust mutex code a bit.
Set robust_head.list_op_pending before trying to lock a robust mutex.
* pthread_mutex_timedlock.c: Likewise.
* pthread_mutex_trylock.c: Likewise.
* pthread_mutex_unlock.c: Likewise for unlocking.
* Makefile (tests): Add tst-robust8.
* tst-robust8.c: New file.
