Improve Worker GC behavior
* dom/ActiveDOMObject.cpp: (WebCore::ActiveDOMObject::hasPendingActivity):

Made hasPendingActivity() virtual, letting Worker add behavior to it.

* dom/WorkerThread.cpp: (WebCore::WorkerThread::workerThread):
Tell message proxy whether there are active objects in the worker whenever JS execution
finishes.

Added a typedef for activeDOMObjects() return type, necessary to declare iterators.

active objects for pending activity.
