We now create bat0 and primary0 independently of the lower mesh interfaces, making the whole setup a lot more robust. In particular: - we can't accidentially destroy primary0 because of concurrent setup and teardown runs of different interfaces - bat0 will always exist, even when no mesh interfaces are up (e.g. no link on wired mesh) - interfaces going down and up again will never tear down the whole of batman-adv - we can enable and disable bat0 independently of the lower interface states
