  Log:
  Contributions from XFS for FreeBSD project:
  - Implement cv_wait_unlock() method which has semantics compatible
    with the sv_wait() method in IRIX.  For cv_wait_unlock(), the lock
    must be held before entering the function, but is not held when the
    function is exited.
  
  - Implement the existing cv_wait() function in terms of cv_wait_unlock().
