Staging: batman-adv: attach each hard-interface to a soft-interface
This patch replaces the static bat0 interface with a dynamic/abstracted approach. It is now possible to create multiple batX interfaces by assigning hard interfaces to them. Each batX interface acts as an independent mesh network. A soft interface is removed once no hard interface references it any longer.
