Events: refactoring
This new version allows to subscribe a client for
an event.
The event should first be created for the API
(the API's prefix is added) using 'afb_daemon_make_event'.
After that, plugins can subscribe or unsubscribe their
clients (identified through requests) to the events that
it generates. See 'afb_req_subscribe' and 'afb_req_unsubscribe'.
Events created by 'afb_daemon_make_event' can be widely
broadcasted using 'afb_event_broadcast' or pushed only to
suscribers using 'afb_event_push'.
Events can be destroyed using 'afb_event_drop'.
