Subject: 	* 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.
	* spin4.c: New; testing spinlocks.
	* barrier1.c: New; testing barriers.
	* barrier2.c: New; testing barriers.
	* barrier3.c: New; testing barriers.
	* barrier4.c: New; testing barriers.
	* GNUmakefile: Add new tests.
	* Makefile: Add new tests.
