mss12: validate display dimensions
...
The code currently reads the coded dimensions from the extradata, but
expects the display dimensions to be set by the caller, and does not
check that they are compatible (i.e. that the displayed size is smaller
than the coded size).
Make sure that when the display dimensions are set, they are also valid.
Fixes possible invalid memory access.

vp9: split last/cur_frame from the reference buffers.
...
We need more information from last/cur_frame than from reference
buffers, so we can use a simplified structure for reference buffers,
and then store mvs and segmentation map information in last/cur.
This prepares the decoder for frame threading support.
