Enable ADST/DCT of dimension 16x16 for I16X16 modes. This change provides benefits mostly for hd sequences. Set up the framework for selectable transform dimension. Also allowing quantization parameter threshold to control the use of hybrid transform (This is currently disabled by setting threshold always above the quantization parameter. Adaptive thresholding can be built upon this, which will further improve the coding performance.) The coding performance gains (with respect to the codec that has all other configuration settings turned on) are derf: 0.013 yt: 0.086 hd: 0.198 std-hd: 0.501 Change-Id: Ibb4263a61fc74e0b3c345f54d73e8c73552bf926
