ipv6: namespace cleanups

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
