New QEMU git repo

[cd2436 at columbia.edu (Christoffer Dall)]

Hi.

So, following advice from Hollis Blanchard, we should implement our
work in upstream QEMU support for KVM and not KVM userspace - sigh.

There is a new repo for this:
  $ git clone git at slice.chazy.dk:qemu.git
  $ git checkout -b armkvm --track origin/armkvm

To push back changes:
  $ git push origin armkvm:armkvm
