Tag broadcasted events with UUID and hop
When API have mutual dependencies, leading to loops in dependecies, broadcasting an event never ends because of the loop (see SPEC-2625). To avoid that weird flood of events, a unic identifier (UUID) is attached to broadcasted event and a tiny memory records previously broadcasted events to avoid re-sending an already sent event. The size of the memory can be set using the macro variable EVENT_BROADCAST_MEMORY_COUNT whose default value is 8. It can be reduced to 0. An other mecanism is added to limit the count of hops that a broadcasted event can do. That count can be set using the macro variable EVENT_BROADCAST_HOP_MAX whose default value is 10.
