Keyframes don't set this variable, so it would use the last set
values from inter frames.

With this, the RD loop properly supports rectangular blocks.

Change-Id: Iece79048fb4e84741ee1ada982da129a7bf00470

Static threshold results slightly up (+0.1% on derf), probably b/c
we now take the filter (sharp/lowpass) into account for the breakout
decision.

Removing redundant code.

Change-Id: I71bfc40a1fb06d8e3149ed5400aa4dfd87a51aac

Combine superblock inter predictors into a unified function that
allows configurable block width and height. The inter predictions
of block sizes smaller than 16x16 are handled differently. To be
continued on merging them later.

* changes:
  Move prediction hit counting to update_state().
  Merge loop over all macroblock modes into encode_sb_row().

So it is consistent with I8x8_PRED.

The probabilities derived from these statistics are used in bitstream
writing; therefore, we should only do this when we actually decide to
use macroblock coding (over superblock coding). Derf gains +0.15%.

The build predictors now output directly to the dest.  These
copies are no longer required.

Change-Id: I8e91eda6b49993e6c16cfadc705d82a7e80f19b2

The intra predictor supports configurable block sizes. It can handle
intra prediction down to 4x4 sizes, when enabled in BLOCK_SIZE_TYPE.

Rename pick_mb_modes to pick_mb_mode, since it now handles only a
single macroblock. This is consistent with pick_sb_mode handling a
single non-macroblock.

This patch changes the default with the modecoefprob expt
to use mode-based forward updates with one-node pegged
modeling.

The maximum difference with fully trained tables is now
less that 0.1%.

Change-Id: I06b44322e10c6703f93f3c1d48d973b1136a0618

These functions now are handled through the common superblock code.

Change-Id: Ib6688971bae297896dcec42fae1d3c79af7a611c

This patch will use the dest buffer instead of the
predictor buffer.  This will allow us in future commits
to remove the extra mem copy that occurs in the dequant
functions when eob == 0.  We should also be able to remove
extra params that are passed into the dequant functions.

* changes:
  tokenize: convert skippable functions
  Add foreach_transformed_block

Change-Id: If69c3d795f87af5cc7bfdfe70ef733c41b4d55c8

Use the common block walker to calculate skippability.

Change-Id: I6721e42f065df237426c91c1d871ec226ba7cdcb

Use subtract_sb* instead.

Change-Id: I3f34140ab97061063a4452945347ef1fe37e13d1

More specifically, remove vp9_quantize_mb*, vp9_optimize_mb*,
vp9_inverse_transform_mb* and vp9_transform_mb*. Instead, use the
generic _sb* functions that take a size argument, and call them with
BLOCK_SIZE_MB16X16.
