We could share the majority of the code. I started by stripping unused
code in their patch (and as you already saw, not quite complete yet).

When Google oss-fuzz supports AFL, we can easily add that support in.
Ultimately it is only the entry function is a bit different. All the
stub functions should work the same.

Regarding all comments below, I will fix them all together in the next
round.

Wei.
