Copy the user provided sockaddr into a normalized sockaddr in rtrequest()
before adding it to the routing table. The rtable code is doing memcmp()
of those rt_dest sockaddrs so it is important that they are stored in a
canonical form. To do this struct domain is extended to include the
sockaddr size for this address family.
