* spinlock.c (__pthread_lock) [HAS_COMPARE_AND_SWAP]: Before doing any
serious work try once whether the lock is uncontested.
Remove duplicate reading of __status before loop.
Change suggested by Hans Boehm <hans_boehm@hp.com>.
* spinlock.h (__pthread_trylock): Remove need for oldstatus variable.
(__pthread_alt_trylock): Likewise.

Memory barrier overhaul following line by line inspection.
* mutex.c (pthread_once): Missing memory barriers added.
* pthread.c (__pthread_wait_for_restart_signal,
__pthread_timedsuspend_new, __pthread_restart_new): Added
memory barriers ``just in case'' and for documentary value.
* spinlock.c (__pthread_release): New inline function for releasing
spinlock, to complement __pthread_acquire. Includes memory
barrier prior to assignment to spinlock, and __asm __volatile
dance to prevent reordering or optimization of the spinlock access.
* spinlock.c (__pthread_unlock, __pthread_alt_lock,
__pthread_alt_timedlock, __pthread_alt_unlock,
__pthread_compare_and_swap): Updated to use new __pthread_release
instead of updating spinlock directly.
* spinlock.c (__pthread_lock, __pthread_unlock, wait_node_alloc,
wait_node_free, wait_node_dequeue, __pthread_alt_lock,
__pthread_alt_timedlock, __pthread_alt_unlock, __pthread_acquire):
Memory barrier overhaul. Lots of missing memory barriers added,
a couple needless ones removed.
* spinlock.c (__pthread_compare_and_swap): testandset optimization
removed, just calls __pthread_acquire, which has the new read
barrier in it before its testandset.

* iconv/gconv.c (__gconv): For flush without output, pass do_flush = 2.
* iconv/skeleton.c: Distinguish do_flush = 1 and do_flush = 2. In the
first case, set outbuf, outstart, outend, and call PREPARE_LOOP before
EMIT_SHIFT_TO_INIT; then pass the output produced by this step down to
the next step. In the second case, clear the state without calling
EMIT_SHIFT_TO_INIT.
* iconvdata/ibm930.c (EMIT_SHIFT_TO_INIT): Use outbuf instead of
