This commit refactors the loop filter selection process to support
variable transform block sizes based filter mask. It disables the
multi-thread loop filter implementation to simplify the experiments.
The speed impact on speed 0 encoding is negligible.

Allow the encoder to drop individual transform block coding.

* changes:
  vp9_dx_iface: move struct defs to separate header
  vp9_decodeframe.h: add missing include

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

Change-Id: Icd4e8e7cdc4b6af6974f87169e50b040ebfe9020

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.

This commit enables the entropy coding of the recursive transform
block partition syntax.

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.

Some fixes for rate control stats and bypass mode.

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

This reverts commit 7f56cb29.

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.
