If a block has all coefficients quantized to zero, the codec will
assume that it uses largest transform block size.

this avoids redefining vpx_codec_vp9_dx, vpx_codec_vp9_dx_algo in
vp9_encoder_parms_get_to_decoder.cc

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.

Width and height of downscaling resolution should not be lower
than min_width and min_height which can be set as needed, both
are 180 for now.

Allows inter and intra tx_types to have different sets of
transforms for different tx_size/sb_type combinations.

This reverts commit 7f56cb29787b187c8cb1b778918ca3b80184c804.
It causes uninitialized reads in the first pass setting up later cost tables.

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.

Remove delta index 254 from probability remapping and subexp coding.
Saves 1-bit when the delta index is 129.

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.
