Under the experiment of CONFIG_LAST4_REF. On derflr testset, using
highbitdepth (HBD), in average PSNR,
(1) LAST2+LAST3+LAST4 obtained +0.361% against LAST2+LAST3;
(2) LAST2+LAST3+LAST4 obtained +1.567% against baesline.

Under experiment CONFIG_LAST3_REF, which can only be turned on when
the experiment of CONFIG_MULTI_REF is on, i.e. LAST3_FRAME can only
be used when LAST2_FRAME is used. CONFIG_LAST3_REF would most likely
be combined with CONFIG_MULTI_REF once the performance improvement
is further confirmed.
On the testset of derflr, using Average PSNR metrics, with HighBitDepth
(HBD) on:
(1) LAST2 HBD obtained +0.579% against base HBD;
(2) LAST2 + LAST3 HBD obtained +0.591% against LAST2 HBD;
(3) LAST2 + LAST3 HBD obtained +1.173% against base HBD.

All the numbers of MAX_MODES have been changed assuming
CONFIG_MULTI_REF. Now correct numbers have been put in for both with and
without the enabling of the experiment MULTI_REF.

Turning on all the other experiments, compared the RD performance
between with and without the use of LAST2_FRAME, on derflr testset,
on Average PSNR:
8-bit: +0.653% (All positive except one,
max: mobile_cif: 2.019%; min: paris_cif: -0.081%)
12-bit HBD: +0.735% (All positive,
max: bridge_far_cif: 2.416%; min: bowing_cif: 0.132%)

Under the experiment CONFIG_MULTI_REF. Current version shows
LAST2 vs base in nextgen on the testset of derflr:
(1) 8-bit: Average PSNR +0.53%
(worst: students_cif: -0.247%; best: mobile_cif: 1.902%)
(2) 12-bit HBD: Average PSNR +0.63%
(worst: pamphlet_cif: -0.213%, best: mobile_cif: 2.101%)
More tuning on the reference frame context design and default
probs are being conducted. This version does not guarantee to
work with other experiments in nextgen. A separate CL will address
the working with all other experiments.

Runborgs results on derflr show consistent results between NEW_INTER
and the previous combination of NEWMVREF and COMPOUND_MODES.

Changes include:
* Uses double for RD cost computation to guard against overflow
for large resolution frames.
* Use previous frame's filter level to code the level better.
* Change precision of the filter parameters.
* Allow spatial variance for x and y to be different

derflr: +0.556% (a little up from before)
Adds an internal buffer in the encoder to store the deblocked
result to help speed up the search for the best bilateral filter.
Very small change in performance but a lot faster:
derflr: +0.518%

This experiment, referred as NEWMVREF, also merged with NEWMVREF_SUB8X8
and the latter one has been removed. Runborgs results show that:
(1) Turning on this experiment only, compared against the base:
derflf: Average PSNR 0.40%; Overall PSNR 0.40%; SSIM 0.35%
(2) Turning on all the experiments including this feature, compared against
that without this feature, on the highbitdepth case using 12-bit:
derflf: Average PSNR 0.33%; Overall PSNR 0.32%; SSIM 0.30%.
Now for highbitdepth using 12-bit, compared against base:
derflf: Average PSNR 11.12%; Overall PSNR 11.07%; SSIM 20.27%.

COMPOUND_MODES experiment encodes separate MV modes for each frame in a compound
reference prediction. Added modes NEAREST_NEARESTMV, ZERO_ZEROMV,
NEW_NEWMV, NEAREST_NEARMV, NEAR_NEARESTMV, NEW_NEARESTMV, NEAR_NEWMV,
NEW_NEARMV, and NEAREST_NEWMV.
Also enhances the wedge-partition expt to work better with compound
modes.

A smooth weighting scheme is used to put more weight
on the intra predictor samples near the left/top boundaries
and decaying it to favor the inter predictor samples more as
we move away from these boundaries in the direction of
prediction.
Results:
derflr: +0.609% with only this experiment
derflr: +3.901% with all experiments

This commit makes a struct that contains rate value, distortion
value, and the rate-distortion cost. The goal is to provide a
better interface for rate-distortion related operation. It is
first used in rd_pick_partition and saves a few RDCOST calculations.

vp9_rdopt is for making rd optimal mode decisions. vp9_rd is for all
other rd related routines. Anything used outside of making an rd optimal
decision belongs in rd.
