Get a list of palette base colors that are used in the above and
left blocks, referred to as "color cache". For each cache color,
signal if it is present in current block's palette, so that we
don't need to transmit their raw values.

When palette-delta-encoding is enabled, compression is improved
by 2% on keyframe and 1% overall for the screen_content testset.

Transmit palette colors with delta encoding.
Coding gain on scrren_content testset:
overall 0.67%  keyframe 1.37%

Mostly refactoring, but a very tiny functional change:
Do all rounding in calc_centroids() itself, instead of rounding in two
places inside palette.c

This gives a slight performance improvement for screen content:
0.078% on average.

About 20% less time spent coding in vp10_k_means().

Change-Id: I5cf7605cde869a269776197bace70de353b07d83

Coding gain on screen_content is 12.2% (was 6.6%).

Some features such as frame-level color buffer, adaptive
entropy coding, are coming in future patches.

The custom LCG is based on the POSIX recommend constants for a 16-bit
rand(). This implementation uses less computation than typical standard
library procedures which have been extended for 32-bit support, is
guaranteed to be reentrant, and identical everywhere.

Account for rounding in distortion calculation in k-means;
carry out rounding before duplicates removal of base colors;
replace numbers with macros;
use prefix increment.

Slight coding gain (<0.1%) on screen_content testset.
