According to rfc 2732 an IPv6 address in a url needs to be enclosed
in [] (e.g. http://[::1]/foobar). Gabbi was not doing this. Instead
it was passing host information directly to its URL generation
routine and just using it. When doing tests against real servers
running on ipv6, this results in failures.
The changes here try to do the bare minumum to get the right results
without changing the create_url method too much. It's likely that in
some future version of gabbi we will want to change a lot here (the
current orientation towards hosts and ports instead of URLs is the
result of the wsgi-intercept integration) but for now we want to
keep the change limited.
I hate myself for the mocks in test_runner. A clear sign of bad
abstraction in runner.py, however this is not the place to be
changing that. Another item for the later list.
