Merge patch which improves performace of forwarding since avoids 2 routing lookups per forwarded packet. Also improves pf_route-to to be more flexible and work correctly on source routing on outgoing traffic rules. Also for bound socket prevent policy routing rules overriding since bound socket need to go the bound interface with the correct source route installed. This also includes the fix for changing default gw bug on FreeBSD but not much hit on pfSense due to its rare usability
