  apparmor: does not provide a way to detect policy updataes

Bug description:
  User space trusted helpers have no way to detect when policy changes
  have been loaded into the kernel. This prevents the applications from
  being able to cache permission queries. Currently trusted helpers have
  not done caching (wish list feature), however the gsetting proxy
  requires userspace caching of permissions due to how gsettings proxy
  has to work.

  This means that policy loads result in stale gsettings policy to
  results in incorrect mediation.

  Add a revision file to the apparmorfs interface that allows detection
  of the current revision number for apparmor policy. This file can be
  read like a pipe, or used via poll, which is sufficient for the
  gsettings proxy detect changes and invalidate its cache.
