net: Add batman-adv meshing protocol

B.A.T.M.A.N. (better approach to mobile ad-hoc networking) is a routing
protocol for multi-hop ad-hoc mesh networks. The networks may be wired or
wireless. See http://www.open-mesh.org/ for more information and user space
tools.

+Description:
+                Each batman node only maintains information about its
+                own local neighborhood, therefore generating graphs
+                showing the topology of the entire mesh is not easily
+                feasible without having a central instance to collect
+                the local topologies from all nodes. This file allows
+                to activate the collecting (server) mode.
