Import patches-unapplied version 1.153 to ubuntu/natty

Imported using git-ubuntu import.

Changelog parent: ce1bd42742

New changelog entries:
  * Update default suite in BuildLiveCD to natty.
  * Use --force-unsafe-io for all dpkg operations.  If we crash we'll just
    destroy the chroot and start from scratch, so syncing is pointless.
