[RFC PATCH 0/2] add fuzzing targets for use with LLVM libFuzzer

libFuzzer[1] is a fuzzing engine included in recent versions of LLVM. It is used by OSS-Fuzz[2] for continuous fuzzing of OSS projects.

This series adds two basic fuzzing targets covering packfile header and index code. It is not particularly portable, and requires the use of LLVM v4.0 (the latest version available on my workstation). I would particularly appreciate advice on how to make the Makefile more portable.
