Subject: Added new routines from POSIX 1003.1j. This is alpha level code.

        * spin.c: New module implementing spin locks.
        * barrier.c: New module implementing barriers.
        * pthread.h (_POSIX_SPIN_LOCKS): defined.
        (_POSIX_BARRIERS): Defined.
        (pthread_spin_*): Defined.
        (pthread_barrier*): Defined.
        (PTHREAD_BARRIER_SERIAL_THREAD): Defined.
        * implement.h (pthread_spinlock_t_): Defined.
        (pthread_barrier_t_): Defined.
        (pthread_barrierattr_t_): Defined.

        * mutex.c (pthread_mutex_lock): Return with the error
        if an auto-initialiser initialisation fails.

        * nonportable.c (pthread_getprocessors_np): New; gets the
        number of available processors for the current process.
