kernel - Add refcount_release_wakeup() and refcount_wait()

* refcount_release_wakeup() releases a reference count and wakes up
  any waiters on the 1->0 transition.

* refcount_wait() waits for the last reference to go away.  When using
  this function all release operations on the field must use
  refcount_release_wakeup().
