mcastmngr: Implement APAS support via VLAN translation.

Add support for APAS by adding VLAN tags to untagged IGMP/MLD packets ingressing on the bridge.

A setup can be done with the following commands where VID 101 is the IPTV VLAN:

uci add network bridge-vlan # =cfg0da1b0

uci set network.@bridge-vlan[-1].device='br-lan'

uci set network.@bridge-vlan[-1].vlan='1'

uci add_list network.@bridge-vlan[-1].ports='eth0.1:u*'

uci add_list network.@bridge-vlan[-1].ports='eth0.2:u*'

uci add_list network.@bridge-vlan[-1].ports='eth0.3:u*'

uci add_list network.@bridge-vlan[-1].ports='eth3:u*'

uci add_list network.@bridge-vlan[-1].ports='eth4:u*'

uci add network bridge-vlan # =cfg0ea1b0

uci set network.@bridge-vlan[-1].device='br-lan'

uci set network.@bridge-vlan[-1].vlan='101'

uci add_list network.@bridge-vlan[-1].ports='eth0.1'

uci add_list network.@bridge-vlan[-1].ports='eth0.2'

uci add_list network.@bridge-vlan[-1].ports='eth0.3'

uci add_list network.@bridge-vlan[-1].ports='eth3'

uci add_list network.@bridge-vlan[-1].ports='eth4:t'
