slicc: support for transitions with a wildcard next state
This patches adds support for transitions of the form:
transition(START, EVENTS, *) { ACTIONS }
This allows a machine to collapse states that differ only in the next state
transition to collapse into one, and can help shorten/simplfy some protocols
significantly.
When * is encountered as an end state of a transition, the next state is
determined by calling the machine-specific getNextState function. The next
state is determined before any actions of the transition execute, and
therefore the next state calculation cannot depend on any of the transition
actions.
