        * ospfd/ospf_interface: (ospf_if_lookup_table) new function to
          lookup oi for a given prefix in a given interfaces table of oi's.
          (ospf_if_new) use ospf_if_lookup_table to deal with zebra
          reporting new interface multiple times.
          NB: This patch is a complete plaster-band of a hack. First, why is
          zebra reporting interface events multiple times? Second, why does
          ospfd maintain so many damn lists and tables relating to oi's -
          these should be reconciled into one or two tables.
