Current mechanism for suspending video decoder is simply creating a blank decoder, but we would still run other relevant tasks in the media pipeline. Eg. running demuxing tasks, MDSM tasks, MRF tasks, video sink tasks. In order to reduce the CPU and battery usage further more, I think we can improve our mechanism by stopping doing some of those tasks as well.

In addition, we don't suspend video which is not in the DOM tree due to bug1346116, we should also seek for a possibility to suspend them.
