vo_vdpau: check maximum video size

Browse Source 
Check the maximum size of video surfaces, and refuse initialization if
the video is too large for them.

Maybe we could do something more sophisticated, like inserting a
software scaler. On the other hand, this would have a very questionable
benefit, as it would be guaranteed to be too slow.
