[global] bump release to 3.2-alpha1

We still have a number of issues to resolve before 3.2 but we're
making good progress (albeit a little overdue). Let's tag the
current tree as an alpha release so that development distributions
(e.g. Fedora rawhide / Debian unstable) can package it and get
more testing.
