ipv6: add 6relayd (RD-, DHCPv6- & NDP-Proxy)
6relayd is an IPv6-tool that relays IPv6-management protocols like router discovery, neighbor discovery and DHCPv6 so that clients on routed (non-bridged) interfaces can use the public address prefix, DHCPv6 and DNS-service of a master interface. This is useful to avoid NAT in chained IPv6-routers. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@34008 3c298f89-4303-0410-b956-a3cf2f4a3e73
