It seems that when bit accounting was introduced in
https://chromium-review.googlesource.com/#/c/400658/
there was one place which was accidentally skipped, leading to build failures
with --enable-dering. This patch adds the missing information.

By default, when building with --enable-accounting the bit accounting
code will collect statistics for every frame while decoding.
Collecting statistics can slow down decode time and we would eventually
like to enable the CONFIG_ACCOUNTING flag by default.
This patch adds a runtime flag so that bit accounting statistics are
only collected when actually needed.

ISO C90 forbids mixed declarations and code and the function
aom_accounting_set_context() was being called before the MB_MODE_INFO

Plus a small code clean up. The experiment of EXT_REFS, compared against
the baseline, using Overall PSNR, now obtains a gain on lowres as:
Avg: -5.818; BDRate: -5.653
Compared against the previous EXT_REFS results on lowres, a tiny gain is
obtained as:
Avg: -0.047, BDRate: -0.063

This commit changes to send frame size explicitly when
error_resilient_mode=1. Purpose is to allow parsing of bitstream
after a packet 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.

This patch adds bit account infrastructure to the bit reader API.
When configured with --enable-accounting, every bit reader API
function records the number of bits necessary to decoding a symbol.
Accounting symbol entries are collected in global accounting data
structure, that can be used to understand exactly where bits are
spent (http://aomanalyzer.org). The data structure is cleared and
reused each frame to reduce memory usage. When configured without
--enable-accounting, bit accounting does not incur any runtime
overhead.
All aom_read_xxx functions now have an additional string parameter
that specifies the symbol name. By default, the ACCT_STR macro is
used (which expands to __func__). For more precise accounting,
these should be replaced with more descriptive names.

While we are at it:
- Rename some variables to more meaningful names
- Reuse some common consts from a header instead of redefining them.

- 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'.
