These are all of the updatable probabilities for binary decisions.
They are only implictly reset on keyframes, making it quite likely for an interframe to desync if a prior frame's header was corrupt or missing outright!

Base parameters for segmentation, i.e.
per-macroblock parameters. These must be kept unchanged even if segmentation is not used for a frame, since the values persist between interframes.

A list of segmentation_map buffers that are to be free()'ed in the next decoding iteration.
We can't free() them right away because the map may still be used by subsequent decoding threads. Unused if frame threading is off.
