2013-06-06New intra mode and partitioning probabilities.Ronald S. Bultje
Split partition probabilities between keyframes and non-keyframes, since they are fairly different. Also have per-blocksize interframe y intramode probabilities, since these vary heavily between different blocksizes. Lastly, replace default probabilities for partitioning and intra modes with new ones generated from current codec. Replace counts with actual probabilities also.
