Michael Froman 5410fc4ddc Bug 1530305 - handle failure to alloc Shmem in RemoteVideoDecoderParent. r=jya
- Modify ProcessDecodedData to return a MediaResult.
- RemoteDecoderParent::RecvInput and RemoteDecoderParent::RecvDrain
  both use error returned from ProcessDecodedData to call SendError.
- RemoteVideoDecoderParent and RemoteAudioDecoderParent both return
  MediaResult with NS_ERROR_OUT_OF_MEMORY if AllocShmem fails in
  ProcessDecodedData (or if the returned buffer size is less than
  the requested size).
