* changes:
Use QuantizeBlock_NEON for VP8EncQuantizeBlockWHT on Arm
Add AArch64 Neon implementation of Intra16Preds
Add AArch64 Neon implementation of Intra4Preds
Add a Neon implementation of Intra16Preds for use on 64-bit Arm
platforms. (This implementation cannot be used on 32-bit Arm
platforms as it makes use of a number of AArch64-only Neon
instructions.)

Add Neon implementation of Intra4Preds for use on 64-bit Arm
platforms. (The same implementation cannot be used for 32-bit Arm
platforms as it uses a number of AArch64-only Neon instructions.)

oss-fuzz does not support dynamic libraries so we stick to
static. But libtiff.a has undefined symbols on Ubuntu, so we
have to disable TIFF.

The lossless encoding speed-ups are:
- up to 1% with default parameters
- up to 4% in cruncher mode: -q 100 -m 6

Apply crop dimensions before calculating scaled width/height to ensure
the check against fuzz_utils::kFuzzPxLimit will use the same dimensions
as the decoder.

Also do not restrict the oss-fuzz script to libfuzzer:
this allows new fuzzer engines to try the script as is.
The libfuzzer restriction is done upstream anyway.

- the tests now build/run/check_build with libfuzzer on oss-fuzz
- centipede is removed as it builds/runs but do not check_build
(timeout due to arguments not parsed correctly)

Change-Id: Id063565fc4cce02fc5e36c7d8499d6de9ff54345
fuzztest is compatible with libfuzzer in compatibility mode, and
fully compatible with centipede by default.

This reverts commit ee26766a89.
This change also reverts the parent.
Revert "Increase the transform bits if possible."
This reverts commit 7ec51c5916.
These changes result in non-lossless encodes.

A 3 by 1 image would not have its 1st and 3rd lines compared at
the second iteration.

This brings minor size improvements because repetitive values in
the transform images are easily explainable through LZ77. Still,
it makes an upcoming pull request a bit more stable.
This is 971a03d820 with a fix to
not forget to analyze the end of the line.
A const has also been added to match VP8LColorSpaceTransform's
signature.

This reverts commit 971a03d820.
Reason for revert:
This creates non-lossless encodes.

Replace the 2d histograms with uint32_t 1d versions (to avoid
pointer casting and to use the optimized VP8LAddVectorEq).

`jpegtran -copy all` may be able to process the file into something
libjpeg can read.

BUGS is described by the man-pages man page as:
A list of limitations, known defects or inconveniences, and other
questionable activities.

Use EXIT_SUCCESS / EXIT_FAILURE in most cases as more granularity isn't
useful. For anim_diff, use 0 (success), 1 (image difference) and 2
(error) to align it with other diff utilities (diff, etc.).

fixes warnings of the form:
/src/dsp/upsampling_sse41.c:170:1: runtime error: implicit conversion
from type 'int' of value -16 (32-bit, signed) to type 'uintptr_t' (aka
'unsigned long') changed the value to 18446744073709551600 (64-bit,
unsigned)
this is the same change as was done previously in upsampling_sse2.c:
2ee786c7 upsampling_sse2.c: clear int sanitizer warnings
