John Cupitt cb1634dd31 block fuzz data over 100kb
Many codecs can take a huge amount of time attempting to read large
random objects. jpeg_read_header(), for example, can take ~10s on a 1mb
of random data.

Ignore fuzz objects over 100kb.

Oscar Mira 3ea72c286e improve fuzz targets and oss-fuzz integration
It replaces current fuzz setup with 5 new fuzzers integrating them with
top-level Makefile. It now supports multiple fuzzing engines and Google's
oss-fuzz. By default, the fuzzers are linked against an standalone runner to
easily reproduce bugs.
