dropping everything but the debian dir

[Michael Gilbert]

hi,

as you've probably just seen, i fixed a bunch of open security issues
(triaged about 40, fixed 20, found the other 20 already fixed, and there
are probably about 40 more issues i didn't get to). anyway, with the
introduction of a patch system and since the upstream files are
maintained in git, every commit is essentially duplicated now.  i think
it would make things a lot easier and cleaner if the upstream files were
dropped from the repo and just the debian dir maintained.  what do you
think?

best wishes,
mike
