PSNR HVS is a human visual system weighted version of SNR that's
gained some popularity from academia and apparently better matches
MOS testing.

This code is borrowed from the Daala Project but uses our FDCT code.

Simple skin detection, from vp8; works reasonable on most of the

Currently, VP9 supports column-tile encoding, which allows a frame
to be encoded in multiple column tiles independently. The number of
column tiles are set by encoder option "--tile-columns". This
provides a way to encode a frame in parallel.

Based on previous set of patches, this patch implemented the tile-
based multi-threaded encoder. Each thread processes one or more
tiles.

Usage:
For HD clips:
--tile-columns=2 --threads=1/2/3/4

While using 4 threads, tests showed that the encoder achieved
2.3X - 2.5X speedup at good-quality speed 3, and 2X speedup at
realtime speed 5.

This change is made in preparation for a
subsequent patch which adds acceleration
for the highbitdepth transform functions.

The highbitdepth transform functions attempt
to use 16/32bit sse instructions where possible,
but fallback to using the C implementations if
potential overflow is detected.  For this reason
the dct routines are made global so they can be
called from the acceleration functions in the
subsequent patch.

The concept:

There's too much noise in source pixels for variance and at low bitrate
the reconstructed looks nothing like the source so we have problems
getting good partitionings with either.   This skirts the issue by using
a box blur scaled down version for variance calculations.  To compare
against source_var_ moved keyframe to be rd based like source_var.

This SSE2 is based on VP8 denoiser's SSE2 code. In VP8, there are
only 16x16 blocks in denoiser, while in VP9, there are 13 different
block sizes.

By adding this SSE2 code, the improvement of encoder speed is around
20%(using C code vs using SSE2 code), vary for different clips.

The unit test for VP9 denoiser is to confirm that the SSE2 code is
bit-exact with the C code. The unit test covers all block size.
