first set of post v7 patches general part of extendTransition optimization, which skips transition breaks (and hence state matching) if vm.extend_transitions is set, and the next CG has only a single choice that does not require a break (e.g. context switch). This is mainly meant to be a state space optimization, and complements the null return on the CG creator side, which is extension/domain specific and also cuts into observability from listeners (no CG - no CG notifications). Note this is only the first part of the patch and probably too general in most cases. The second part extends this with an interface that can control breaks dynamically (e.g. from listeners). Added a ChoiceGenerator.setCurrent() (empty by default) that can be used as a CG type specific hook to expand/modify choices once the CG becomes active Added the first part of the patch that allows SUT context expansion of EventChoiceGenerators, which is required to make the new event system work in situations that need to add additional events based on the current SUT state (e.g. statemachines with timeout events). Fix for INVOKEDYNAMIC causing a NPE for recycled/restored function objects (Nastaran's patch)
