The ABI version isn't the same as the product version. It was moved to
3.0.0 in 0MQ/3.1.0.

It's fun and quite easy to test a hypothesis like "we absolutely need
accurate ABI versioning".

If no-one makes a pull request with a patch, and takes ownership of
the problem over time, we can be quite confident that the problem
isn't really there, or isn't serious enough to worry anyone.
