57f180b388 Removed bmi from blockd
This originally was "Removed update_blockd_bmi()".  Now,
this patch removed bmi from blockd and uses the bmi found
in mode_info_context.  Eliminates unnecessary bmi copies between
blockd and mode_info_context.

There were 4 variants of the quantize loop in vp9_quantize.c, now
there is 1.

c849eaca59 Use b_width/height_log2 instead of mb_ where appropriate.
Basic assumption: when talking about transform units, use b_; when
talking about macroblock indices, use mb_.

called together, this commit merged them into a single function for

ff2b8aa2c9 Contextual entropy coding of partition syntax
This commit enables selecting probability models for recursive block
partition information syntax, depending on its above/left partition
information, as well as the current block size. These conditional
probability models are reasonably stationary and consistent across
frames, hence the backward adaptive approach is used to maintain and
update the contextual models.

It achieves coding performance gains (on top of enabling rectangular
block sizes):
derf:   0.242%
yt:     0.391%
hd:     0.376%
stdhd:  0.645%

31ee193a9c Extension of segmentation to 8 segments.
Also some further simplification following removal
of top node code.

There is an issue in regards to the shared file vp8cx.h
in regard to the roi_map as this interface assumes that
there are only 4 segments. I have left the value here as
4 for now meaning that the roi_map interface is broken
for VP9.

Note that this change would have been easier if I hadn't
had to search for hard wire instances of the number 4
and <= 3.

138ec38cab Convert coeff to per-plane MACROBLOCK data
This commit moves the coeff storage from the MACROBLOCK struct to its
per-plane part. The next commit will remove the coeff member from the
BLOCK structure so that it is consistently accessed per-plane.

Also refactors vp9_sb_block_error_c and vp9_sb_uv_block_error_c to be
variable subsampling aware.

a26c1edbb4 Enable rectangular support for comp inter-intra
This commit enables rectangular block prediction of compound
inter-intra mode. It combines the mb/sb32/sb64 prediction functions
into a unified version with configurable block width and height.
This fixes the enc/dec mismatch of the codebase when
comp-interintra-pred is enabled.
