This commit tries to do UV intra mode coding adaptive to Y intra mode. Entropy context is defined as conditional PDF of uv intra mode given the Y mode. All constants are normalized with 256 to be fit in 8 bits. This provides further coding efficiency beyond the quantizer adaptive y intra mode coding. Consistent gains were observed on all clips and all bit rates for HD all key encoding tests. To test, configure with --enable-experimental --enable-uvintra Change-Id: I2d78d73f143127f063e19bd0bac3b68c418d756a
