* debian/patches/fix-nova-rootwraper-env.patch: Dropped
  no longer needed.
* debian/nova-compute-{kvm,xen,uml,lxc}.conf: Add the connection
  type "--connection=libvirt" since libvirt is no longer the default.
* debian/nova.conf: Define connection_type=libvirt in common nova.conf
  instead of nova-compute-*.conf until Bug #921294 is addressed.
