Communicate pulldown flags to clients to fix VC-1 playback with pulldown content

Browse source 
The pulldown flags should be communicated to the client of the libavcodec library. Not doing so causes jerky playback with pulldown content. Note that this change requires the patch previously provided here: http://ffmpeg.org/pipermail/ffmpeg-devel/2011-April/110314.html
