Python 3.2

Update the Python 3 stack in Fedora from 3.1 to 3.2

Fedora 14 schedule currently has feature freeze on 2010-07-27

Upstream release schedule currently has first alpha release on 2010-06-26, final release on 2010-12-11

So for Fedora 14 to have Python 3.2 we'd have to ship a pre-release version. Given that Python 3 isn't on the critical path, that's not unreasonable.

Lining up the schedules (as of 2010-05-28):

We're now compiling Python3 with support for computed goto's in the interpreter mainloop. This can speedup execution of python code by as much as 17%. https://bugzilla.redhat.com/show_bug.cgi?id=566770
