user applications and libs which interface to FFmpeg or libavformat
through a URLProtocol or AVIOContext receive the AVPacket.data but
not AVPacket.side_data but the side data is often essential

With this patch, such applications can set the flag and would
receive the complete data stream. The alternative would be for such
libs to be redesigned to interface to FFmpeg or libavformat
differently
