batman-adv: substitute tt_poss_change with a per-tt_entry flag
tt_poss_change is a node-wide flag which tells whether the node is in a roaming state (a client recently moved to/away from it) in order to let it apply special re-routing rules. However this flag does not give a clear idea of the current state because it is not possible to understand *which client* is actually involved in the roaming. For this reason a better approach has been chosen: instead of using a node-wide variable, the roaming state is now given by a per-tt_entry ROAM flag which, in case of packet coming through the node, tells the node whether the real destination is in roaming state or not. With this flag change, batadv_check_unicast_ttvn() has also been rearranged in order to better fit the new re-routing logic and to be much more readable.
