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.

ecd39520b8 avcodec/h264: Partially decode and display single fields try #2 
This like the previous attempt does not fully correctly decode this
type of non standard H.264, but it now works fully automatic
requiring no manual filters or flags to be used

  h264: increase MAX_SLICES to 32

The available sample decodes correctly before, but the reporter of the bug
claims that this change reduces artifacts. This is thus merged
If someone has samples that decode differently depending in the MAX_SLICES
value, please open a ticket on trac.
Also this change should be reverted if it turns out that the artifacts
that where seen had a different cause

fc567ac49e avcodec: Add padding after the remaining AVFrames 
This limits ABI issues in case libavcodec is linked to a libavutil with larger AVFrame
Which can happen if they are shiped in seperate binary packages and libavutil is upgraded

A cleaner alternative would be to replace them by pointers but this would likely cause
a small speedloss
