CrOS fuzzing: Allow devs to fuzz more structured data

Project Member Reported by jorgelo@chromium.org, Jun 15 2018

Issue description

It's not immediately obvious how to properly fuzz more elaborate data structures like protobufs and GL command buffers. Moreover, we don't have enough guidance as to how to prevent the fuzzer from failing initial sanity checks in the target code.
