Modified Files:
	src/sys/net: if.c if.h
	src/sys/netinet: ip_output.c
	src/sys/netinet6: in6.c in6_src.c ip6_mroute.c ip6_output.c nd6_rtr.c

Log Message:
use if_indexlim (instead of if_index) and ifindex2ifnet[x] != NULL
to check if interface exists, as (1) if_index has different meaning
(2) ifindex2ifnet could become NULL when interface gets destroyed,
since when we have introduced dynamically-created interfaces.  from kame
