        * lib/version.h: add ZEBRA_URL (unused for now)
        * lib/vty.c: CMD_ERR_NOTHING_TODO when reading conf file should not
          be fatal. slight reformating.
        * ospfd/ospf_zebra.c: ignore reject/blackhole routes if zebra sends
          these type of routes. probably should be a new type of route to
          allow daemons to more easily choose whether to redistribute them
          - rathen than just a flag (eg for reject/blackhole).
          reorder the is_prefix_default test for ZEBRA_IPV4_ROUTE_DELETE to
          avoid the inverted test - slightly more readable.
        * redhat/zebra.spec.in: Add ospfapi port to services file, if
          with_ospfapi.
        * zebra/rib.h: Change nexthop types to an enum.
        * zebra/rt_netlink.c: run it through indent -nut.
          Add nexthop_types_desc[] descriptive array for nexthop types.
          (netlink_route_multipath) debug statements indicate which branch
          they are in and print out nexthop type.
        * zebra/zebra_rib.c: slight reformatting.
        * zebra/zebra_vty.c: Pass ZEBRA_FLAG_BLACKHOLE flag to
          static_add_ipv4() if Null0 route is configured. print out Null0 if
          STATIC_IPV4_BLACKHOLE route, and ignore flags (shouldnt be
          possible to set flags from vty) for config and show route.
