New changelog entries:
  [ Steve Langasek ]
  * live-build/functions: mount tmpfs on /var/cache/apt and var/lib/apt, so
    we don't have to leave empty space in our derivative images for packages
    that have been downloaded/installed/removed.  This normally isn't
    relevant for the installed system, since the root filesystem will
    auto-expand in place on the target disk, but lets us ship smaller
    images.
  * live-build/functions: also call 'apt-get update' after mounting the
    blank /var/lib/apt.
  * live-build/ubuntu-cpc/hooks/033-disk-image-uefi.binary: call apt-get
    update *before* installing packages, not after.
  [ Robert C Jennings ]
  * live-build/ubuntu-cpc/functions: Add a function, teardown_mountpoint,
    to reverse the work done in setup_mountpoint.  Lack of this function
    has forced users of setup_mountpoint to implement this separately
    and the implementations have diverged. (LP: #1716992)
  * live-build/ubuntu-cpc/functions: Remove umount_settle function.
    The was only used where teardown_mountpoint was lacking.
  [ Steve Langasek ]
  * Also adjust live-build/ubuntu-server/hooks/032-installer-squashfs.binary
    to use teardown_mountpoint.
