error_resilience: move the MECmpContext initialization into ER code
...
Currently, it needs to be initialized by the ER caller (which is
currently either a mpegvideo decoder or h264dec). However, since none of
those decoders use MECmpContext for anything except ER, it makes more
sense to handle it purely inside ER.

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.
