rtnetlink: Extend rtnetlink to support RTNLGRP_IPV4_IFADDR and

Browse Source 
RTNLGRP_IPV6_IFADDR.

This commit renames the rtnetlink-link.{c,h} to rtnetlink.{c,h}
and extends the module to support RTNLGRP_IPV4_IFADDR and
RTNLGRP_IPV4_IFADDR multicast groups.  A later patch will start
using this module to react to interface address changes.
