Functions
void	aw_clear_q (aw_event_q_t *q)
	Destroy all events, use factory if f != NULL, clear q.
aw_event_t *	aw_create_event (aw_event_context_t context, aw_cache_allocator_t *f)
	Create an event, use factory if f != NULL.
void	aw_destroy_event (aw_event_t *e)
	Destroy an event, use factory if f != NULL.
aw_event_t *	aw_dup_event (const aw_event_t *e, aw_cache_allocator_t *f)
	Duplicate an event, use factory if f != NULL.
int32_t	aw_event2n (aw_event_t *e, int32_t size, byte_t *buffer)
	Convert an event into network format, copy into buffer.
void	aw_event_format (aw_event_t *e, byte_t *format, byte_t *s, u_int32_t size)
	Fill s with format, replacing: $v with event value, $n with event name, $p with event priority, $t with timestamp.
const aw_event_t *	aw_findin_q (const aw_event_t *e, const aw_event_q_t *q)
	Search for matching event in q (mamcmp all but next ptr).
int32_t	aw_n2event (aw_event_t *e, const byte_t *buffer)
	Fill an event from buffer with data in event network format. NOTE: e->sig.id must filled by caller!
