In addition, I don't think RIPng should require link-local addresses
even over multicast network.

If RIPng doesn't use link-local addresses as the source address,
routed can determine the interface where RIPng comes by checking its
source address with address of interface.

Currently, routed require special interface to determine the
interface (ask ND, or extented recvfrom()).
