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.

This CL will facilitate adapt_scan experiment.
In adapt_scan experiment, dynamic scan order will be stored in
AV1_COMMON

* 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).
Handle the sub8x8 chroma component at the unit of 2x2/4x2/2x4 level
and use the motion vector inherited from the luma component. This
improves the coding performance:
lowres 0.4%
midres 0.25%
hdres 0.15%

The av1_mv_class0_tree is a balanced tree with two leafs and can
simply be coded as a boolean with probability class0[0].
If CLASS0_SIZE is ever changed from 1, this change will need to be
reverted.

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.

In a previous commit: 5db9743fbb, two
changes that appeared to be typos are breaking build when experiments
are enabled:
../../libvpx/configure --enable-experimental --enable-ref-mv
--enable-ext-intra --enable-ext-refs --enable-ext-interp
--enable-supertx --enable-var-tx --enable-entropy --enable-ext-inter
--enable-ext-tx --enable-motion-var --enable-dual-filter
--enable-ext-partition --enable-ext-partition-types
--enable-loop-restoration --enable-rect-tx --enable-palette
--enable-aom-highbitdepth --enable-filter-intra --enable-internal-stats
&& make clean && make -j16
This commit fixes the issue.

For example, loops of the form:
"for (i = 0; i < 1 + max_value; ++i) ..." or
"for (i = 0; i <= max_value; ++i) ..." are possibly infinite loops,
theoretically speaking (even if practically, they aren't).
So, compiler cannot optimize those loops.
When possible, I rewrote such loops to be finite even theoretically.
