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.

This commit replaces the offset based block index calculation with
incremental based one. It does not change the coding statistics.

Allow the transform size writing, reading, and the reconstruction
process to support rectangular transform block size coding.

This commit allows the partition context model to account for the
maximum transform block size of the coding block.

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:

This ensures TGs can be decoded even if the whole
frame has not been received and the frame length
is not known.

This is a manual adaptation of the following commit from aom/master:
ce12003d60a1c8d6c65ed07ba165c34062fcbcbd
The original commit message:
A tile group is a set of tiles in scan order.
Each tile group has a version of uncompressed and compressed headers,
identical apart from tile group parameters.
Encoding probability updates takes account of the number of
headers to control overheads.
The decoder supports arbitrary numbers of tile groups with
arbitrary number of tiles. The number of tiles in a TG is
signalled in the uncompressed header for that TG.
The encoder currently only supports a fixed number
of TGs (3, when error resilient mode is on) of equal size
(except possibly for the last one).
The average BDR performnce with 3 tile groups versus
anchor with error resilient mode and up to 16 tiles is:
NR YCbCr: 3.02% 3.04% 3.05%
PSNRHVS: 3.09%
SSIM: 3.06%
MSSSIM: 3.05%
CIEDE2000: 3.04%

Previously, when ext-partition-types and either clpf or dering were
enabled, the signalling for clpf/dering would not be encoded or decoded,
as the code to do so was inside a #if !CONFIG_EXT_PARTITION_TYPES block.
This caused many tests (eg, AV1/EndToEndTestLarge.EndToEndPSNRTest/0)
to fail with encode/decode mismatches.

- Eliminate the awkward _av1 suffix/infix in local variable names.
- Lift bitdepth selection out of the token loop.

Ran some manual sanity checks:
- Verified that the automatically generated encodings match the
hand-written encodings before the patch.
- Verified that the encoded bitstream before/after this patch is
identical.

When building with --enable-daala_ec, the tx_type for intra blocks can be
coded using the CDFs that are updated once per frame.
This patch converts a tx_type symbol to be coded with aom_write_symbol()
and aom_read_symbol() that was missed in f3e8e267.
