RLC has timers. We need to keep track of time. We chose to not use realtime but 'processing time'. That is we send a tick to RLC for every subframe when it is processed by the softmodem. Before this commit we used to increase time in the function mac_rlc_status_ind which may not be called every subframe (especially in TDD mode). So we need another way to keep track of time. We introduce rlc_tick() and call it in eNB_dlsch_ulsch_scheduler, which is called every subframe, both in FDD and TDD. We also call rlc_tick() in the function ru_thread_synch() because pdcp_run() and rrc_rx_tx() are called there too. It may not be the best solution. To be revised if needed. Note: the UE has not been touched. Some modification is needed for the UE too, most probably.
