Bump to hacking 1.1.0

This brings in a couple of new checks which must be addressed, many of
which involve a rather large amount of changes, so these are ignored for
now. A series of follow-up changes will resolved these.

'pycodestyle' is added as a dependency rather than it being pulled in
transitively. This is necessary since we're using it in tests.
