We extract the dealing of direct tasks from the TailDispatcher object and move into to the existing nsThread and TaskQueue classes. TaskQueue is made to work with do_QueryInterface. We continue accessing the direct tasks dispatcher via the TailDispatcher for now, which itself will forward the dealing of such tasks to the underlying thread.
