kefren e8941bb5d0 * rework the reattachment code
* build an implnull label when a route is added and let mpls_add_label
  to take care of relabelling
* take out last piece of the code where we do route lookups - we should have
  every information we need in labels
* tested these changes using a number of rump kernels and some couple of
  thousands of flapping routes
