ec6fb649da Partition the ans experiment into 'ans' and 'rans'
The (new) ans experiment replaces the bool coder with uABS bools. The
'rans' experiment adds multisymbol coding.

This matches the setup in aom/master.

368fbc955d Fix warnings reported by -Wshadow: Part2b: more from av1 directory
From code only part of nextgenv2 (and not aomedia)

03f6fdcfca Fix warnings reported by -Wshadow: Part1b: scan_order struct and variable
- Change struct name to all caps SCAN_ORDER to be locally consistent.
- Rename struct pointers to 'scan_order' instead of hard to read short
  names 'so' and 'sc'.

Cherry-picked from aomedia/master: 30abc082

526484482a Code cleanup: mainly rd_pick_partition and methods called from there.
- Const correctness
- Refactoring
- Make variables local when possible etc
- Remove -Wcast-qual to allow explicitly casting away const.

Cherry-picked from aomedia/master: c27fcccc
And then a number of more const correctness changes to make sure other
experiments build OK.

8043cc4018 Use Daala entropy coder to code bits.
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.

b100db7c1d Wrap palette code inside CONFIG_PALETTE flag.
This flag was already added to aomedia/master, so bringing it back to
webm/nextgenv2, as part of an effort to get the two codebases in sync.

9ed1a2ff44 Remove custom rans types
(cherry picked from aom/master commit 11206c60d930be9d29100567aa67f2a65463852a)

Includes renames in a bunch of places not handled by the original
due to differing tree states.

4ce69de9a6 Remove add_token_no_extra.
It was a fairly small production optimization for VP9.

ceebb70197 Refactor expand dry_run types to return coef rate
Adds the functionality to return the rate cost due to
coefficients without doing full search of all modes.
This will be subsequently used in various experiments,
including in new_quant experiment to search quantization
profiles at the superblock level without repeating the
full mode/partition search.

3c42c09608 Further changes to new-quant tables
Refactor to streamline the number of profiles needed, in
preparation for the next steps.

NO change in performance.

33590f8c71 Rename rans_dec_lut to rans_lut
It's used in both encoding and decoding. Matches (historical)
implementation in aom/master.
