contrib: add some basic scaffolding for some fuzz test targets
I'd like to get the majority of our C code covered by automated fuzz
testing. I've started with bdiff because it was already decoupled from
libpython and therefore was fairly quick to produce a working
fuzzer. The code here is a little odd because I've been having trouble
convincing libfuzzer to define a main and I threw in the towel.
This code will also work with github.com/google/oss-fuzz, and once it
lands in our main repo I intend to enable automated fuzzing in
oss-fuzz with reports going to our security alias.
