Remove rwlock wrappers

Browse Source 
The only remaining consumer of the rwlock compatibility wrappers
is ztest.  Remove the wrappers and convert the few remaining
calls to the underlying pthread functions.

    rwlock_init()    -> pthread_rwlock_init()
    rwlock_destroy() -> pthread_rwlock_destroy()
    rw_rdlock()      -> pthread_rwlock_rdlock()
    rw_wrlock()      -> pthread_rwlock_wrlock()
    rw_unlock()      -> pthread_rwlock_unlock()

Note pthread_rwlock_init() defaults to PTHREAD_PROCESS_PRIVATE
which is equivilant to the USYNC_THREAD behavior.  There is no
functional change.
