IP4 Router Alert option handling for IGMP

and a new ip4-options node, inserted between ip4-input and ip4-punt,
that checks for IP-router-alert option + IGMP combination and sends
the packet to the ip4-local. This is required because some IGMP
packets are sent to the group address and not the all-routers address.
All IGMP packets are sent with the router alert option.
