fsm: Introduce default time-out handling
If a FSM doesn't specify any timer_cb, simply terminate the FSM by default on time-out. This is a reasonable default for most cases, and avoids copy+pasting a one-line timer_cb function in every FSM. Also, even if there is a timer_cb, let it have a return value to decide if the core should terminate after return from timer_cb or not. Change-Id: I0461a9593bfb729c82b7d1d1cf9f30b1079d0212
