Modified Files:
        syssrc/sys/netinet: if_arp.c if_ieee1394arp.c

Log Message:
better support for multiple IPv4 addresses on a single interface.
- consider non-primary (2nd and beyond) IPv4 address as "local", and prevent
  outgoing ARP.
- for routing entries generated by ARP, make sure to set rt->rt_ifa equal to
  rt_key, to help IPv4 source address selection for traffic to myself.
PR 13311.

caveats/TODOs:
- interface routes ("connected routes" in cisco terminlogy) is tied with the
  primary (1st) IPv4 address on the interface.  should be fixed with updates
  to rt_ifinit().
- source address selection for offlink locations.  1st address tend to be used
  with the current code
  (you can configure it right by setting rt->rt_ifa accordingly).
