        * ospf_packet.c:  (ospf_associate_packet_vl) cleanup, move
          some of the checks up to ospf_read, return either a
          virtual link oi, or NULL.
          (ospf_read) Cleanup, make it responsible for checks. Remove
          the nbr lookup - moved to ospf_neighbor. Adjust all nbr
          lookups to use new wrappers exported by ospf_neighbor.
        * ospf_neighbor.h: Add ospf_neigbour_get and ospf_nbr_lookup.
        * ospf_neighbor.c: (ospf_neigbour_get) Index ospf_interface
          neighbour table by router-id for virtual-link ospf_interfaces,
          not by peer_addr (which breaks for asymmetric vlinks)
          (ospf_nbr_lookup) add a wrapper for nbr lookups to deal with
          above.
