In the UE, we wish to handle ^C in the UE to send a message before terminating, so we allow custom wait handlers to implement such functionality. Use itti_wait_tasks_unblock() to unblock itti_wait_tasks_end(). Also, implement itti_wait_tasks_end() using semaphores, as signals are not async-signal-safe (and therefore should not be used in a signal handler).
