replaced ThreadInfo.yield() (which was bypassing SyncPolicy) with SyncPolicy.setsRescheduleCG(). The current use is only for the corner case where the last transition in the last non-daemon triggers a defect in a still runnable daemon, which we want to detect before the daemon is shut down.
Added ChoiceGenerator.set/getStateId(), which is set on the nextCg once we broke a transition and performed state matching. This can be used to determine the states in the current path without having to maintain this as a separate structure that just mirrors the CG path. There is always a 1:1 relationship between the state that caused the CG and the respective CG instance.
