This commit increases the minimum size for allocated buffer for
compressed data. The old size underestimated the size needed for
small images with width or height less than 64 pixels.

This commit resets the transform size to be the maximum possible
value. It avoids out-of-boundary writing when the ActiveMap is
turned on.

This avoids an encoding segmentation fault in speed 5, due to the
use of uninitialized dummy inter prediction filter buffer in the
dynamic motion vector referencing scheme.

The difference between src and dst will be signed, the error will be
unsigned. The change quiets -fsanitize=integer:
unsigned integer overflow: 4294967295 * 4294967295

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.

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.

* changes:
Palette: Use inverse_color_order to find color index faster.
Rewrite some loops to avoid -Wunsafe-loop-optimizations warnings.
Remove some useless casts
Add compiler warning flag -Wextra and fix related warnings.
Declare some array sizes to be constants (known at compile time).
