Compare token cost of pack_mb_tokens/pack_txb_tokens with token cost
from rate-distortion loop. If there is any difference, dump out mode
info.

The EC_ADAPT experiment cannot work unless EC_MULTISYMBOL is also
enabled.
This patch replaces all individual checks with a centralized check in
both the bitreader.h and bitwriter.h.

The new ec_multisymbol experiment supersedes the rans experiment and is
used for multisymbol features that can be backed by either daala_ec or
rans.
This experiment is automatically enabled by ec_adapt and will try to
enable daala_ec or ans (in that order).

This experiment performs symbol-by-symbol statistics
adaptation for non-binary symbols. It requires DAALA_EC or
RANS and ANS to be enabled. The adaptation is currently
based on a simple recursive filter and is taken from
Daala. It has an adaptation rate dependent on alphabet size,
taken from Daala. It applies wherever non-binary symbols
are encoded using Cumulative Probability Functions rather
than trees.
Where symbols are adapted, forward updates in the compressed
header are removed.
In the case of RANS coefficient token values are adapted,
with the exception of the zero token which remains a
binary symbol. In the case of DAALA_EC other values
such as inter and intra modes are adapted as CDFs are
provided in those cases.
The experiment is configured with:
./configure --enable-experimental --enable-daala-ec --enable-ec-adapt
or
./configure --enable-experimental --enable-ans --enable-rans \
--enable-ec-adapt
EC_ADAPT is not currently compatible with tiles.
BDR results on Objective-1-fast give a small loss:

The (new) ans experiment replaces the bool coder with uABS bools. The
'rans' experiment adds multisymbol coding.
This matches the setup in aom/master.

Added aom_write_tree_cdf() and aom_read_tree_cdf() function calls to
bitwriter.h and bitreader.h respectively.
These calls take a multisymbol CDF and an index and directly encode the
symbol using the enabled entropy coder.
Currently only the daala entropy encoder supports this (enabled with
--enable-daala_ec) and a compile error is thrown otherwise.

When building with --enable-daala_ec, calls to aom_write_tree() and
aom_read_tree() will convert a aom_tree_index structure with associated
aom_prob probabilities into a CDF on the fly for use with the
od_ec_encode_cdf_q15().
The number of symbols in the CDF is capped at 16, and trees that contain
more than 16 leaf nodes are handled by splitting the most likely, e.g.,
highest probability symbols, first and coding multiple symbols if
necessary.

When building with --enable-daala_ec, calls to aom_write() and aom_read()
use the daala entropy coder to write and read bits.
When the probability is exactly 0.5 (128), then raw bits are used.

This brings it in line with the Daala CDFs and will make it easier to
share code.

(cherry picked from aom/master commit af98507ca928afe33e9f88fdd2ca168379528d6a)
Rename av1_write_tree() to aom_write_tree() and move it into bitwriter.h
to match aom_read_tree() in bitreader.h.
