Update.
* 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. * condvar.c: Likewise. * internals.h: Likewise. * join.c: Likewise. * manager.c: Likewise. * mutex.c: Likewise. * pthread.c: Likewise. * rwlock.c: Likewise. * semaphore.c: Likewise. * signals.c: Likewise.
