Alexander V. Chernikov 75b893375f Add support for RFC 6598/Carrier Grade NAT subnets. to libalias and ipfw.
In libalias, a new flag PKT_ALIAS_UNREGISTERED_RFC6598 is added.
 This is like PKT_ALIAS_UNREGISTERED_ONLY, but also is RFC 6598 aware.
Also, we add a new NAT option to ipfw called unreg_cgn, which is like
 unreg_only, but also is RFC 6598-aware.  The reason for the new
 flags/options is to avoid breaking existing networks, especially those
 which rely on RFC 6598 as an external address.
