Reason for revert:
Breaks webrtc.linux
Original issue's description:
> Add Jpeg frame writer for test support.
>
> Also, use it to save worst psnr frame in video quality tests. It is indented that these saved frames from perfbots will be uploaded to the cloud and will be available in chrome perf dashboard. Because of that size of the saved frame is somewhat an issue. Also, y4m is not convenient to view.
