Drawing a line to the scope of Python packaging

This is sort of silly – numpy ought to provide a helper, so you could write install_requires=[np.get_abi_version_constraint(), ...] or something. And I don’t think anyone actually does this correctly right now.

This idea is also being discussed in more detail at Support for build-and-run-time dependencies - #37 by jdemeyer (@njs: no I’m not trying to hijack this thread, this is a good-faith attempt to move the ABI-compatibility discussion in one place).
