c28ed1d743 h264: move [uv]linesize to the per-slice context
While it is a per-frame variable, it is only really used in the
low-level decoding code, so it is more efficient to store it in the
slice context.

a12d3188cb h264: use a smaller struct for the ref lists
There is no need to store a whole H264Picture, with a full AVFrame
embedded in it. This should allow getting rid of the embedded AVFrame
later.

51d8725a6e h264: use the main H264Context as the parent for all slice contexts
There is now no need to have per-slice copies of the H264Context.

been moved to the per-slice context

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.
