[ospfd] Restructure opsf_if_update() and ospf_network_run()

    Add an struct interface paramenter and adjust the affected
    code accordingly.

    The old code was a mess looping over all interfaces several times
    when one interface was added/changed.

    * ospfd/ospfd.h: Add struct interface parameter to ospf_if_update()
    * ospfd/ospf_zebra.c: Add ifp arg to ospf_if_update() calls.
      (ospf_interface_address_delete) delete ospf_if_update() call,
      redundant as function calls ospf_if_free() itself.
    * ospfd/ospfd.c: (ospf_network_unset) handle deconfiguration here,
      rather than ospf_if_update.
      (ospf_network_run_interface) ospf_network_run, for
      any given interface.
      (ospf_network_run) move guts to previous, and use it.
      (ospf_if_update) Adjust to take struct interface as argument, as
      all callers have a specific ifp in mind.
      Iterate over ifp's connected list and call ospf_network_run_interface
      instead of ospf_network_run, turning this path into O(nm) rather
      than O(n^2).
      Adjust all code dealing with opsf_if_update and ospf_network_run to
      pass the new struct interface * arg.

     (some minor modifications and bug-additions by Paul Jakma).
