fsm_event	event
	Event to be handled in state function.
struct timespec	now
	Time when the event occurred.
struct timespec	timeout
	Time of next timeout.
struct timespec	timer
	Time of next timer expiration.
int(*	state )(struct robo_fsm *fsm)
	Pointer to current state function.
int(*	last_state )(struct robo_fsm *fsm)
	Pointer to previous state function.
int(*	fnc_stack [10])(struct robo_fsm *fsm)

int(**	fnc_sp )(struct robo_fsm *fsm)
	Pointer to the top of fnc_stack.
int	debug_states
	Whether to print debug messages on state transitions.
char *	debug_name
	The name of automaton (printed in debug messages).
Event sending synchronization
sem_t	event_noticed
	This semaphore is "put" after a event is noticed by fsm and prepared for handling.
