This replaces the pthread rwlock with a new implementation that uses a
more scalable algorithm (primarily through not using a critical section
anymore to make state changes). The fast path for rdlock acquisition and
release is now basically a single atomic read-modify write or CAS and a few
branches. See nptl/pthread_rwlock_common.c for details.
