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.
