539e5ac2ec examples/qsvdec: free the lavc decoder before closing MFX/VAAPI 
lavc expects MFX to still be in a usable state on close.

3ee462dca1 examples/qsvdec: do not free the surfaces in the frame_free() callback 
Even though libmfx might not need them anymore, avcodec might still
access the surfaces. So free them separately at the end.

078be09dd7 examples/demuxing_decoding: abort decoding when width, height or pix_fmt change 
This is necessary, because avcodec_decode_video2 can change
width, height and/or pixel format of the AVCodecContext. Since
video_dst_data and video_dst_linesize are not updated by calling
av_image_alloc again, av_image_copy[_plane] asserts, because the
destination buffer is too small.

In this case, creating a useable rawvideo is not possible anyway, since
it has fixed width/height/pix_fmt.

b0352b1997 avcodec: export motion vectors in frame side data on demand 
The reasoning behind this addition is that various third party
applications are interested in getting some motion information out of a
video "for free" when it is available.

It was considered to export other information as well (such as the intra
information about the block, or the quantization) but the structure
might have ended up into a half full-generic, half full of codec
specific cruft. If more information is necessary, it should either be
added in the "flags" field of the AVMotionVector structure, or in
another side-data.

This commit also includes an example exporting them in a CSV stream.
