Locate them (code-wise) in frame_context, and have them be updated as any other probability using the subexp forward and adaptive bw updates. See issue 1040 point 1. TODOs: - real-world default probabilities - why is counts sometimes NULL in the decoder? Does that mean bw adaptivity updates only work on some frames? (I haven't looked very closely yet, maybe this is a red herring.) Change-Id: I23b57b4e5e7574b75f16eb64823b29c22fbab42e
