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.

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).
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.

The av1_token encodings must match the contents of the aom_tree_index
structures so generate all encodings from the symbol trees.

The bug was introduced here:
https://chromium-review.googlesource.com/#/c/399975/4/av1/encoder/bitstream.c
In that patch, I had removed 2nd declaration of a variable of the same
name. But it turns out that the two variables actually had a different
type (even though the name was same).
Now, we keep both variables, but rename one of them -- that fixes the
mismatch. While we are at it, made both variables local as well.
The fix can be verified as follows:
../../libvpx/configure --enable-experimental --enable-supertx
--enable-var-tx --enable-entropy --enable-internal-stats && make clean
&& make -j16

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
(1) 780952 Add encoder first pass support to bi-prediction in EXT_REFS
(2) f91498 Add pred prob handling for new references in EXT_REFS
(3) e91472 Add decoder support for bi-direct prediction in EXT_REFS
(4) 0dbac9 Add encoder support to new references in EXT_REFS
(5) ad70cc Remove hard-coded number for EXT_REFS
(6) 9c1e2f Add the use of new reference frames at encoder in EXT_REFS
(7) 6d4fde Add the experiment flag of EXT_REFS

- Use range check function to avoid DCT_DCT overflow.
We need to re-develop the column txfm side scaling/rounding. Now,
we prefer to maintain the current BDRate level.
- Encoder user level time reduction <1% owing to av1_fht32x32_avx2.
- Add MemCheck unit test and fdct32() unit test.
