This is a partial reland of https://webrtc-codereview.appspot.com/39939004/. The original CL was reverted because ViECapturer use ResetSize/IsZeroSize on |captured_frame_| as a check to make sure each captured frame is only delivered once. Removing ResetSize introduced a race condition where a captured frame could be delivered multiple times. I have fixed this problem in this CL by replacing ResetSize with scoped_ptr::release.
