batman-adv: add basic bridge loop avoidance code
This second version of the bridge loop avoidance for batman-adv avoids loops between the mesh and a backbone (usually a LAN). By connecting multiple batman-adv mesh nodes to the same ethernet segment a loop can be created when the soft-interface is bridged into that ethernet segment. A simple visualization of the loop involving the most common case - a LAN as ethernet segment: node1 <-- LAN --> node2 | | wifi <-- mesh --> wifi Packets from the LAN (e.g. ARP broadcasts) will circle forever from node1 or node2 over the mesh back into the LAN. With this patch, batman recognizes backbone gateways, nodes which are part of the mesh and backbone/LAN at the same time. Each backbone gateway "claims" clients from within the mesh to handle them exclusively. By restricting that only responsible backbone gateways may handle their claimed clients traffic, loops are effectively avoided.
