lavf: add av_guess_frame_sample_aspect_ratio function
Guesses the sample aspect ratio of a frame, based on both the stream and the frame aspect ratio. Since the frame aspect ratio is set by the codec but the stream aspect ratio is set by the demuxer, these two may not be equal. This function tries to return the value that you should use if you would like to display the frame. Basic logic is to use the stream aspect ratio if it is set to something sane otherwise use the frame aspect ratio. This way a container setting, which is usually easy to modify can override the coded value in the frames.
