Modified Files:
        src/share/man/man9: rwlock.9

Log Message:
clarify how rw_{write,read,lock}_held() work; rw_write_held() actually
returns non-zero only if current lwp is the owner, the other two don't care
about owner; also warn that functions are not atomic, and thus should only
ever be used to assert that the lock is held
