The backbone gw check has to be VLAN specific so that code using it can specify VID where the check has to be done. In the TT code, the check has been moved into the tt_global_add() function so that it can be performed on a per-entry basis instead of ignoring all the TT data received from another backbone node. Only TT global entries belonging to the VLAN where the backbone node is connected to are skipped. All the other spots where the TT code was checking whether a node is a backbone have been removed. Moreover, batadv_bla_is_backbone_gw_orig() now returns bool since it used to return only 1 or 0.
