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.

7ea1b3472a lavc: deprecate the use of AVCodecContext.time_base for decoding 
When decoding, this field holds the inverse of the framerate that can be
written in the headers for some codecs. Using a field called 'time_base'
for this is very misleading, as there are no timestamps associated with
it. Furthermore, this field is used for a very different purpose during
encoding.

Add a new field, called 'framerate', to replace the use of time_base for
decoding.

0652e024c6 h264: reset ref count if decoding the slice header fails 
Otherwise the ER code might try to use some already freed references.

Fixes possible access to freed memory.

7f0e81db3c h264: limit allowed pred modes in ff_h264_check_intra_pred_mode() to 3 
Higher modes are not allowed for 16x16/chroma, which is what this
function is used for. Otherwise this function would return 0 (vertical
prediction) for invalid higher modes, which could result in invalid
reads.

d1b3fabe69 h264: reset first_field if frame_start() fails for missing refs 
In this case we may not have a current frame, while first_field being
set implies we do.

Fixes invalid reads.

  h264: check that execute_decode_slices() is not called too many times

Conflicts:

The check is replaced by an assert() as the mb index should not ever go out
of bounds.
