* 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%

* changes:
Define SIMD_INLINE using AOM_FORCE_INLINE
AOM_FORCE_INLINE: fix always_inline attribute
Free memory allocated by daala_ec encoder.
Move clpf_sse4_1.c to clpf_sse4.c in agreement with convention
sync avg_test.cc with aom/master
av1_init_scan_order
initialize data structures related to adaptive scan order
av1_update_scan_prob
update nonzero probabilities from nonzero counts
av1_augment_prob
embed r + c and coeff_idx info with nonzero probabilities.
When sorting the nonzero probabilities, if there is a tie,
the coefficient with smaller r + c will be scanned first
av1_update_sort_order
apply quick sort on nonzero probabilities to obtain a sort order
av1_update_scan_order
apply topological sort on the nonzero probabilities sorting order to
guarantee each to-be-scanned coefficient's upper and left coefficient
will be scanned before the to-be-scanned coefficient.
av1_update_neighbors
For each coeff_idx in scan[], update its above and left neighbors in
neighbors[] accordingly.

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

- 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.

The (new) ans experiment replaces the bool coder with uABS bools. The
'rans' experiment adds multisymbol coding.
This matches the setup in aom/master.

Move STAT_TYPE enum to source file.
Code cleanup: mainly rd_pick_partition and methods called from there.
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.

Currently the RD loop traverses 4X8 blocks in inverted N order while
the bitstream stores blocks smaller than 8x8 in Z order. This causes a
discrepancy where the RD loop reads uninitialized data while
performing intra prediction. As a temporary fix simply disable the
use of the extended right edge for 4X8 blocks, until the bitstream can
be changed to match the logical structure of the blocks.

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

- Refactoring
- Make variables local when possible etc
- Remove -Wcast-qual to allow explicitly casting away const.

experiments build OK.
