Bug description:
  [Impact]
  aptdaemon needs to implement frontend locking to avoid it hijacking dpkg status lock from clients that do implement frontend locking; and in order to be protected from apt clients that acquire the status lock (which they won't do if aptdaemon holds the frontend lock).

  This also change the locking order to lock in APT order, and the
  unlock order becomes the reverse of that so that the behavior is sane
  wrt other clients, as it was somewhat broken.

  [Test case]
  Lock /var/lib/dpkg/lock-frontend and then try do so something with aptdaemon, it should not be possible until you release lock-frontend.

  [Regression potential]
  There may be other race conditions appearing now due to the order of (un)locking changing.
