Untested revamp of barrier.c.

        * barrier.c: Still more revamping. The exclusive access
        mutex isn't really needed so it has been removed and replaced
        by an InterlockedDecrement(). nSerial has been removed.
        iStep is now dual-purpose. The process shared attribute
        is now stored in the barrier struct.
        * implement.h (pthread_barrier_t_): Lost some/gained one
        elements.
        * private.c (ptw32_threadStart): Removed some comments.
