c377e04d8a h264: move top_borders into the per-slice context 
Also change the method for allocating to the same one as used by
edge_emu_buffer.

36d04801ba h264: move the scratch buffers into the per-slice context 
Also change the method for allocating them. Instead of two possible
alloc calls from different places, just ensure they are allocated at the
start of each slice. This should be simpler and less bug-prone than the
previous method.

167e004e1a h264: drop any pretense of support for data partitioning 
It does not work correctly and apparently never did. There is no
indication that this (mis)feature is ever used in the wild or even that
any software other than the reference supports it.

Since the code that attempts to support it adds some nontrivial
complexity and has resulted in several bugs in the past, it is better to
just drop it.

cf1e0786ed 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.
