Backed out changeset 7799cfb99362 (Bug 517804 - Flush reflows and invalidations during viewWillDraw) because it caused a ts_shutdown regression.

Bug 517818. Suppress seeking to the end of the stream on Resume, there is no data to read there. r=kinetik

Bug 516740. Never simplify the visible region by increasing its area when we're subtracting opaque areas from the visible region. Instead, just don't subtract the opaque area if it would make the visible region too complex. r=bzbarsky

Bug 513144. Make nsMediaChannelStream::CloneData clone the underlying cache stream, which adds the new stream as co-owner of all the nsMediaCache blocks currently cached for the original stream. Also, use NS_NEW_RUNNABLE_METHOD instead of the SuspendedStatusChanged class. r=doublec

Bug 513144. Move ownership of the Ogg decoder's nsMediaStream out from nsChannelReader to nsOggDecoder. Also remove unnecessary mNotifyOnShutdown flag from nsOggDecoder and nsWaveDecoder. Since Load can only be called once after Init, remove unnecessary initialization of variables in Load and move some code up from Load to Init in both backends to simplify Load. r=doublec
