a71ce1cf74 animencoder_fuzzer: fix error check w/Nallocfuzz 
WebPAnimEncoderAdd() may fail due to muxer errors that are reported as
booleans. When running under the nallocfuzz engine, ignore all failures.

Found by Nallocfuzz (https://github.com/catenacyber/nallocfuzz).

This function may fail due to allocation failures. Use the
NALLOC_FUZZ_VERSION environment variable to detect the engine. This was
added in:

cc3577e9b9 fuzzer/*: use src/ based include paths 
this synchronizes the code with chrome, where this format allows the
code to pass buildtools/checkdeps/checkdeps.py

83604bf3ac {animencoder,enc_dec}_fuzzer: convert some abort()s to returns 
with functions that can legitimately fail when under memory pressure the
fuzzer should exit gracefully rather than abort().

+ add some more error detail to output

bd94090a11 import fuzzers from oss-fuzz/chromium 
+ a simple makefile + README

these were mostly equivalent, chromium added support for
WEBP_REDUCE_CSP.

the file names were normalized as follows:

fuzz_advanced_api.{c,cc} -> advanced_api_fuzzer.c
fuzz_animation_api.{c,cc} -> animation_api_fuzzer.c
fuzz_webp_animencoder.cc -> animencoder_fuzzer.cc
fuzz_demux_api.{c,cc} -> demux_api_fuzzer.c
fuzz_webp_enc_dec.cc -> enc_dec_fuzzer.cc
fuzz.h -> fuzz_utils.h
fuzz_simple_api.{c,cc} -> simple_api_fuzzer.c

Bug: webp:409
