Brings back most of Jim's previous patch for choosing
partitioning based on variance while making it compatible
with the current state of the code. Also adds a
nonrd_use_partition() function to recursively encode  for any
arbitrary sb_type decisions within a 64x64 block; and
includes some refactoring.

Currently, when the VAR_BASED_PARTITIONING mode is turned on
for speed 7, there is a 10+% speed-up observed.

Experiments/improvements with this new partitioning method
will be conducted subsequently.

This commit adjusts the rate-distortion modeling for non-RD mode
decision. It puts more weights on energy from AC coefficients when
estimating the cost. The coding performance for rtc testset is
improved by 0.72%.

Assign interp_kernel value in MACROBLOCKD. This will be used to
select prediction filter coefficient sets and generate motion
compensated prediction.

more readable as well.

The block size used for non-RD mode decision in FIXED_PARTITION
setting was uninitialized. This commit fixes it by setting block
size to be BLOCK_16X16.

Adds a fast diamond search which is about 5% faster than FAST_HEX
with only a 0.1% drop in psnr when turned on for both speeds 5 and 7.
This search is turned on for speed 7.

This commit allows the non-RD mode decision to skip mode RD modelling
check, if the motion vector associated with the current mode is
same as that of NEARESTMV mode. This makes speed -7 about 2% faster.
Previous change that converts cost metric from SAD to model based RD
value makes the codec 6% slower at speed -7.

The rate-distortion model in non-RD coding mode is only applied to
luma component. This commit removed a few redundant addition steps.

Change-Id: Id8edc0a47c2dbef8deba43debe2c95db39454de3

This commit replaces SAD cost with modeled rate-distortion cost
for non-RD mode decision. It translates the prediction residual
SSE into estimate rate and reconstruction distorion costs, hence
capturing the quantization setting effect. The compression
performance of speed -7 for rtc set is improved by 14.79%.
