* barrier.c: Remove static initialisation - irrelevent

	for this object.
	* pthread.h (PTHREAD_BARRIER_INITIALIZER): Removed.
	* rwlock.c (pthread_rwlock_wrlock): This routine is
	not a cancelation point - disable deferred
	cancelation around call to pthread_cond_wait().

tests/ChangeLog:
	* spin1.c: New; testing spinlocks.
	* spin2.c: New; testing spinlocks.
	* spin3.c: New; testing spinlocks.
