Prepare TVLV infrastructure for more packet types, in particular the upcoming batman-adv multicast packet type. For that swap the OGM vs. unicast-tvlv packet boolean indicator to an explicit unsigned integer packet type variable. And provide the skb to a call to batadv_tvlv_containers_process(), as later the multicast packet's TVLV handler will need to have access not only to the TVLV but the full skb for forwarding. Forwarding will be invoked from the multicast packet's TVLVs' contents later.
