Running 'make namespacecheck' shows:
net/ipv6/route.o
ipv6_route_table_template
rt6_bind_peer
net/ipv6/icmp.o
icmpv6_route_lookup
ipv6_icmp_table_template
This addresses some of those warnings by:
* make icmpv6_route_lookup static
* move inline's out of ip6_route.h since only used into route.c
* move rt6_bind_peer into route.c
