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)
Bug: oss-fuzz:69508
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.

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.

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

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.).
Bug: webp:637

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
Change-Id: I36064d837ad1a7a118918c16a5551fc732dec2ff
This avoids attempting to allocate 0 bytes if the call fails. (An
additional byte is added to the result to allow a '\0' to be appended.)

Options can precede the file name. This still won't be correct for
Unicode file names, but an approximation will be displayed (with '?'s)
rather than the first character if kParams.file_name were used.
glutCreateWindow() looks like it will prohibit correcting this as it
expects an ASCII string.
