In decoder, the scaling calculation, such as (mv * x_num / x_den),
is fairly time-consuming. In this patch, we check if the scaling
happens or not at frame level, and then decide which function to
call to skip scaling calculation when no scaling is needed. Tests
showed a 3% decoder performance gain.

Now that the predictor is the dest, we do not need the
extra parameters.

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.

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.

This is work-in-progress, it implements multiple ARF
encoding behind an experimental flag.

It adds the ability to insert multiple ARF frames into a
single ARF group. This patch implements the reordering
of the coded frames, and implements a fixed-length coding
pattern. It applies a fixed quantizer strategy based on
where the frame is in the coding sequence.

Further work to modify the rate control strategy is
ongoing and will be submitted via a set of future patches.

In this first step, each ARF group is recursively
bisected and an ARF frame added at that position in the
sequence. The recursion continues until ARF frames are
within MIN_GF_INTERVAL frames.

The code sits behind the "multiple-arf" experimental
flag ("CONFIG_MULTIPLE_ARF"). The experimental flag
"oneshotq" ("CONFIG_ONESHOTQ") also needs to be enabled
for this patch to work correctly.

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.

To match the order of  directional intra prediction modes for larger
blocks, also renamed the i4x4 prediction modes to mirror the larger
variants.

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%.

Change-Id: I196814c070a7c79889590658ce10a6eb07454389

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.

Change-Id: I7399ec2512393aa98aadda9813ca0c83e19af854

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.

less that 0.1%.

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.

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.
