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.

This decoder control requires AV1 to be compiled with --enable-accounting.
Note that bit accounting data is only available after a frame has been
decoded.

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

Limit the recursive transform block partition depth to 2. For a
32x32 transform block unit, one can maximally go down to 8x8 transform
block size.

Check the encoding statistics. If all the coding blocks use the
max transform size, skip transform size coding in the frame header.

Skip counting the inter transform block size distribution for
the intra transform block size coding.

Cherry-pick Daala b5020bee:
Remove redundant test in od_ec_decode_bool_q15().
Using a test that decodes 100M random binary symbols, making this change
produced a speed up of 8.81% with gcc-4.9.3 and 3.71% with clang-3.7.1,
both compiled with -O2.
