IMO, it made sense to have different directories and tests for v4.0 vs.
v4.1, given the protocol differences, but v4.2 is a set of extensions
to the v4.1 protocol. I don't think we're well served by creating all a
bunch of extra infrastructure for that when we can just extend the v4.1
stuff.

The tests in this patchset treat v4.2 functionality as optional. If the
server advertises it, they will test it. That may not make sense for
everything, but it should work well enough here.
