* lib/filer.c: show protocol name in filter_show()
    * lib/plist.c: show protocol name in vty_show_prefix_entry()
    * routemap.c: show protocol name in vty_show_route_map_entry()
    * lib/vty.c: in vty_command(), show protocol name if command unknown

    * zebra/zserv.c: Always provide distance fo route add

    * ripd/rip_snmp.c: rip2IfConfReceive() sends values in conformance
      with RFC. Also PeerDomain is now set to a STRING type.
    * ripd/ripd.h: rip_redistribute_add() API includes metric and distance
    * ripd/ripd.c: rip_redistribute_add() API i.e. stores metric and distance
      Now allows a RIP-route to overcome a redistributed route coming
      from a protocol with worse (higher) administrative distance
      Metrics from redistribution are shown in show ip rip
    * ripd/rip_zebra.c: adapt to the rip_redistribute_add() API, i.e.
      provide distance and metric
    * ripd/rip_interface.c: adapt to the rip_redistribute_add() API
    * ripd/rip_routemap.c: no RMAP_COMPILE_ERROR on (metric > 16) usage
      rather a CMD_WARNING, because set metric ius shared with other
      protocols using larger values (such as OSPF)
      The match metric action takes first external metric if present
      (from redistribution) then RIP metric.
