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.

====================================
Testing head checking code: Case B-4
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.

Category B: simple case involving pruned changesets
TestCase 4: multi-changeset branch, all are pruned

.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * old branch is pruned
..
.. expected-result:
..
.. * push allowed
