static

Determine which buffers golden and altref should be updated with after this frame.

The spec isn't clear here, so I'm going by my understanding of what libvpx does

Intra frames update all 3 references Inter frames update VP56_FRAME_PREVIOUS if the update_last flag is set If the update (golden|altref) flag is set, it's updated with the current frame if update_last is set, and VP56_FRAME_PREVIOUS otherwise. If the flag is not set, the number read means: 0: no update 1: VP56_FRAME_PREVIOUS 2: update golden with altref, or update altref with golden
