Sourceware and patchwork 2.0

[Siddhesh Poyarekar]

Update before I put things down for the day:

- The patchwork instance is now at 2.2.0-rc1
- I've created a virtualenv with django and other dependencies, at 2.2.8
  right now since that's what patchwork supports
- Overall situation is still the same: manage.py runserver works
  perfectly fine with all data intact.  apache modwsgi however doesn't.

The moment the last bit is resolved, we're good to go with patchwork
with all data conserved.  Patches since the last week or so will be
missing though since the server upgrade rendered the patchwork scripts
unusable.
