* SkEventDispatcher() - Event Dispatcher
*
* Description:
* The event dispatcher performs the following operations:
* o while event queue is not empty
* - get event from queue
* - send event to state machine
* end
*
* CAUTION:
* The event functions MUST report an error if performing a reinitialization
* of the event queue, e.g. performing level Init 0..2 while in dispatcher
* call!
* ANY OTHER return value delays scheduling the other events in the
* queue. In this case the event blocks the queue until
* the error condition is cleared!
*
* Returns:
* The return value error reported by individual event function
