  Modified files:
    sys/kern             vfs_lookup.c 
   - Get rid of PDIRUNLOCK, instead, we fixup the lock state immediately after
     calling VOP_LOOKUP().  Rather than having each filesystem check the
     LOCKPARENT flag, we simply check it once here and unlock as required.
     The only unusual case is ISDOTDOT, where we require an unlocked vnode
     on return.  Relocking this vnode with the child locked is allowed since
     the child is actually its parent.
   - Add a few asserts for some unusual conditions that I do not believe can
     happen.  These will later go away and turn into implementations for these
