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

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).
Note: some of these warnings are enabled by a combination of -Wunused
(added earlier) and -Wextra.

* 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
- 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 tell functions return an unsigned integer.
This causes the AV1.TestTell test case to fail because
-1 is greater than 20 when treated as an unsigned integer.

Fix warnings reported by -Wshadow: Part1: aom_dsp directory
Move STAT_TYPE enum to source file.
Code cleanup: mainly rd_pick_partition and methods called from there.
The bit accounting functions aom_reader_tell() and aom_reader_tell_frac()
return the number of bits and 1/8th bits respectively.
This patch changes the return type from ptrdiff_t which is signed to
uint32_t which is unsigned.
The size_t type is not used since we only care about the number of bits
or 1/8 bits per entropy coder context and we don't expect to code more
than 512 megabits per tile.

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.

- Change struct name to all caps SCAN_ORDER to be locally consistent.
- Rename struct pointers to 'scan_order' instead of hard to read short
names 'so' and 'sc'.

This flag was already added to aomedia/master, so bringing it back to
webm/nextgenv2, as part of an effort to get the two codebases in sync.

To get ready for pulling AV1 to nextgenv2
Replace the experimental flag by MOTION_VAR. Rename major variables.

* changes:
Remove custom rans types
Remove add_token_no_extra.
Remove unused aom_rans_build_cdf_from_pdf
Add the tool used to generate the constrained tokenset.
Remove the starting zero from ANS CDFs.
Import the aom_read/write_symbol abstractions from aom/master
(cherry picked from aom/master commit 11206c60d9)
Includes renames in a bunch of places not handled by the original
due to differing tree states.
