Add a new option - BRIDGE_VLANDB_ENTRY_TUNNEL_ID which is used to dump the tunnel id mapping. Since they're unique per vlan they can enter a vlan range if they're consecutive, thus we can calculate the tunnel id range map simply as: vlan range end id - vlan range start id. The starting point is the tunnel id in BRIDGE_VLANDB_ENTRY_TUNNEL_ID. This is similar to how the tunnel entries can be created in a range via the old API (a vlan range maps to a tunnel range).
