Resolve a rare enc/dec mismatch issue triggered by the 4x4 chroma block size in sub8x8 block coding. To avoid using 2x2 chroma block size, it always uses the top-left 4x4 luma block coding information to predict the 4x4 chroma block. The rest 3 4x4 luma blocks will be coded independently without coding the collocated chroma blocks. The compression performance gains are 1.45% for lowres set (down from 2.4% of the original cb4x4 design). Change-Id: Iff560fcab172ed4219434d5174c4d8dfbbb04135

Properly scale the chroma component block size to handle the sub8x8 coding block in the encoding stage. It resolves the large performance drop issue in cb4x4 due to minimum 4x4 block size. Change-Id: Ia2477b43521408b72a20aca406f495faba66c033

Fix the intra prediction boundary availability check for chroma components. Such intricacy is due to the re-schedule of sub8x8 chroma coding block to avoid 2x2 prediction and transform size. Change-Id: I4a2dff8743cf78af8dfb90265019e8d1222ed734

Previously the transform type sets used for 16x32/32x16 transform sizes corresponded to 16x16 transforms. Now they correspond to 32x32 transforms with a reduced available set. BDRATE impact: 0.05% worse for lowres, 0.13% worse for midres Change-Id: I01d405d497c13837f5404f9e0caf8c571f3b26cf

The ATTRIBUTE_PACKED caused something to break in MB_MODE_INFO. boundary_info got corrupted and moving InterpFilter around in MB_MODE_INFO could cause a segfault or the problems to go away (for instance by moving InterpFilter to the end of the struct). Perhaps something in MB_MODE_INFO is sensitive to alignment. This should be investigated further and get fixed or documented, but for now remove the attribute.
