Rework the rate distortion optimization pipeline. Use precise
distortion metric that accounts for the forward and inverse
transform rounding effect.

This commit makes the coefficient token packtization process account
for variable transform block sizes supported in a single processing
block. It fixes an enc/dec mismatch issue when var-tx, ext-tx, and
misc-fixes experiments are all turned on.

Properly update the transform type counts in key frame coding at
decoder. It fixes an enc/dec mismatch issue when both ext-tx and
misc-fixes are turned on.

Set increase_denoising parameter for temporal filter.

Adjust variance threshold, delta-qp, and intra penalty cost,
based on estimated noise level in source.

Replace denoising_on with a level value=L/M/H.

EXT_TX introduces some new symbols to be decoded.
The encoder counts how many times these are used.
In multithreaded mode, the counts from the worker threads
need to be accumulated into the main thread.

This change means that VP10/VPxEncoderThreadTest now works
with more choices of cpu-used and number of passes.

Add a cast on a double to unsigned assignment.

Properly reset the early termination flag in the recursive transform
block partitioning rate-distortion optimization scheme.

Change-Id: Ibfe918f21f11dcb1ec267c09f954c635305cc95a

Use inter_block_yrd as rate-distortion optimization for lossless
coding. This fixes transform coefficient buffer swap use case and
resolves the unit test failure related to lossless coding.

Disbales threading test for speeds > 0 and all modes other than
2-pass temporarily.

The old workaround "p = 0 ? 0 : p -1" is misleading.

?: happens before =
assigning back to p truncates to one byte.

Therefore it is equivalent to (p - 1) & 0xFF, but the check just exists
to work around a first pass bug, so let's make the work around more
clear.

This commit properly resets the recursive transform block partition
array in the settings of using largest transform block size at frame
header level. It fixes one of the unit test failure related to the use
of frame level fixed transform block size with 440 color format.

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.

are turned on.

Bug relating to issue:- http://b/25090786

base_frame_target is supposed to track the idealized bit
allocation based on error score and not the actual bits
allocated to each frame.

The clamping of this value based on the VBR min and max pct values
was causing a bug where in some cases the loop that adjusts the
active max quantizer for each GF group was running out of bits at
the end of a KF group. This caused a spike in Q and some ugly artifacts.

A second change makes sure that the calculation of the active
Q range for a group DOES, however, take account of clamping.

This commit makes the recursive transform block partitioning properly
handle the non-420 color format. It resolves an enc/dec mismatch
issue in that setting when var-tx experiment is turned on.

partitioning experiment due to merge conflict.

Periodically estiamte noise level in source, and only denoise
if estimated noise level is above threshold.

Add the row and column index to the argument list of unit functions
called by foreach_transformed_block wrapper. This avoids the
repeated internal parsing according to the block index.
