d40ae0e595 h264: do not copy qscale when updating per-thread contexts
It's a per-slice quantity constructed when parsing the slice header.

0dea4c77cc h264: only ref cur_pic in update_thread_context if it is initialized
It may be empty if the previous thread's decode call did not contain a
valid frame.

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.

init_dimensions() does that explicitly, Size changes are detected by
