Bug description:
  When upstream D-Bus merged the AppArmor mediation patches, they did
  not like the GetConnectionAppArmorSecurityContext() bus method.
  Instead, they decided to expose a peer's AppArmor context using the
  org.freedesktop.DBus.GetConnectionCredentials() bus method. All users
  of the GetConnectionAppArmorSecurityContext() method should switch to
  the GetConnectionCredentials() method as soon as possible so that
  Ubuntu can drop the patch that implements
  GetConnectionAppArmorSecurityContext() by the time 16.04 LTS is
  released.

  In order to switch to the new method, you'll need to depend on
  libapparmor 2.10 or newer.

  I'll be adding example code that illustrates how to switch from
  GetConnectionAppArmorSecurityContext() to GetConnectionCredentials().

  content-hub, media-hub, mediascanner2, signon-apparmor-extension,
  ubuntu-download-manager, and ubuntu-system-settings-online-accounts
  all need to transition to the new method of obtaining the AppArmor
  label.

  The apparmor package should be updated to drop the libapparmor-
  mention-dbus-method-in-getcon-man.patch patch and the dbus package
  should be updated to drop the aa-get-connection-apparmor-security-
  context.patch patch.
