  Log:
  For snapshots we need all VOP_LOCKs to be exclusive.
  
  The "business class upgrade" was implemented in UFS's VOP_LOCK
  implementation ufs_lock() which is the wrong layer, so move it to
  ffs_lock().
  
  Also, as long as we have not abandonned advanced vfs-stacking we
  should not preclude it from happening: instead of implementing a
  copy locally, use the VOP_LOCK_APV(&ufs) to correctly arrive at
  vop_stdlock() at the bottom.
