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.

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.
