mgw: Initial IPv6 support
This commit contains the bulky work of moving all address parsing to
support IPv6 together with IPv4.
Some specific patches required for full IPv6+IPv4 support requiring
behavioral changes come after this one.
Full Osmux IPv6 support is left out of the scope of this patch.
