Improving model rd with variance and quant step
Improves the rd modeling function and implements them using interpolation
from a table which is a little faster. Also uses sse as input to the
modeling function rather than var - since there is no dc prediction
used and as a result the sse works a little better.

Yunqing Wang [Wed, 19 Jun 2013 00:09:50 +0000 (17:09 -0700)]
Add two-pass quantization
Optimized the quantization function by making it a two-pass
process. The first pass does a quick checking of the transform
coefficients against the base ZBIN, and only keep the good
enough set of coefficients for quantization. A skipping
check is added. If all coefficients are within the base ZBIN, no
quantization is needed. The second pass is the actual quantization
pass, which only processes the coefficient subset determined
in first pass. This reduces the computation. Furthermore, an
alternitive method is used for large transform size, which often
has sparse nonzero quantized coefficients.
Overall, the encoder speedup is about 4%. The quantization function
itself gets 20% faster.

The original fdct32x32 that allows higher intermediate precision (18

Fix chroma output when scaling
The encode-side scaling was not indexing through the image correctly
for the chroma planes, causing a green checkerboard-like output in
the unit test.

Minor change in forward updates
Removes the case of coding prob = 0 for forward updates, since that
is not an allowed probability to code.
Slightly improves efficiency but may not matter in practice.

Fix partition coding of corner block
This commit fixed the allowable partition types for bottom-right

When a block has over half of its pixels as valid content in both
vertical and horizontal directions, allow all the four partition
types in the bit-stream. Otherwise, apply partition type constraints.
