mpegvideo: Split picture allocation for encoding and decoding
...
The main ff_alloc_picture() function is made more generic with all the
parameters necessary as arguments. This will allows to move most of the
related functions to a separate file later.
Right now wrappers are provided to try and minimize the number of
changes in the code.

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.
