vp9: split last/cur_frame from the reference buffers

Multimedia / Libav - Ronald S. Bultje [gmail.com] - 11 August 2016 03:53 UTC

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.
