This experiment still requires review from AOMedia due to
conflicts with other adopted experiments.

Adds the CfL experiment flag and computes a block-level DC_PRED that is
required by CfL in order to compute alpha_cb and alpha_cr.

The rate-distorsion impact of computing DC_PRED at the prediction block level
for chroma planes is rather small

This experiment complexifies DSP function dispatch, without bringing
any real value (it's non-normative arbitrary behaviour).
Moreover, it only has an effect on obsolete transforms, the new ones
don't implement this mechanism.

experiment such that we can evaluate each feature's performance
separately

This new coding tool is targeted to add new inter compound modes using
single reference frame - initially NEAREST_NEARMV for single reference
prediction.

This reduces the multiplier width of daala_ec from 16x15->31 to
8x15->23, which reduces hardware latency by an estimated 20% (and
area for this module by an estimated 40%).

These are the smallest logical changes required to achieve this,
but the approach will be optimized significantly in subsequent
commits.

This new coding tool is targeted to complete following two tasks:
(1) Remove the inter mode NEWFROMNEARMV;
(2) Add new inter coding modes that provide compound prediction but
    using single reference frame - initially NEAREST_NEARMV from
    single reference.

Adds a dependent config flag 'interintra' to turn on/off interintra
modes altogether.
Adds a dependent config flag 'wedge' to turn on/off wedge compound
for both interinter and interintra.

Adds another macro to change wedge predictors to use
only 0, 1/2, or 1 weights.

From now, use
--enable-ext-inter --enable-wedge --enable-interintra to get the
same behavior as the old --enable-ext-inter.

Frame Super-Resolution is an experiment currently under development.
This commit just adds an experimental flag for it.

The goal of the experiment is to compress a downsampled version of a
frame instead of the full resolution one when bandwidth is limited. The
decoder will need to upsample and filter the frame it recieves after
decoding. It is thought that this will result in a visually superior
result in low bandwidth scenarios.

Currently, this supports playback, zooming, and printing bit accounting
 statistics to stdout.
The configure script does not yet build the analyzer, to compile it:

 libaom.a `wx-config --cppflags` `wx-config --libs` -o analyzer
