* fix reschedule issue
* correct code formatting
* Fix isScheduled
* improve a bit performance of executing functions in cocos thread
* added test to verify reschedule issue
* re-init timer in schedule if timer exists and alive
If the delta time dt passed to cocos2d::Timer::update(float) is longer than the
interval of the timer, then the timer will be triggered several times even if
the selector is unscheduled during the call.
This commit adds a flag in cocos2d::Timer stop the update loop if the selector
has been unscheduled.
* Fixing issue where Scheduler::unscheduleAll() would not unschedule functions scheduled with Scheduler::performFunctionInCocosThread.
* Removing clear of _functionsToPerform from unscheduleAll, based on code review feedback. Adding a function removeAllFunctionsToBePerfomedInCocosThread, which will remove all pending functions scheduled with performFunctionOnCocosThread.
* Adding test case for Scheduler::removeAllFunctionsToBePerformedInCocosThread
* Adding proper cleanup code to Scheduler test for SchedulerRemoveAllFunctionsToBePerformedInCocosThread
