* sysdeps/pthread/pthread.h: Add prototypes for pthread_spin_init,
	pthread_spin_destroy, pthread_spin_lock, pthread_spin_trylock,
	and pthread_spin_unlock.
	* sysdeps/pthread/bits/pthreadtypes.h: Change struct _pthread_fastlock
	into pthread_spinlock_t.  Change all uses.
	* spinlock.c: Implement pthread_spin_lock.
	Rename __pthread_unlock to __pthread_spin_unlock and define weak
	alias for real name.
	Define pthread_spin_trylock, pthread_spin_init, and
	pthread_spin_destroy.
	Change all uses of _pthread_fastlock to pthread_spinlock_t.
	* spinlock.h: Rename __pthread_unlock to __pthread_spin_unlock.
	Change all uses of _pthread_fastlock to pthread_spinlock_t.
	* Versions [libpthread] (GLIBC_2.2): Add pthread_spin_init,
	pthread_spin_destroy, pthread_spin_lock, pthread_spin_trylock,
	and pthread_spin_unlock.
	* cancel.c: Use __pthread_spin_unlock instead of __pthread_unlock.
	Change all uses of _pthread_fastlock to pthread_spinlock_t.
