-   @short An abstract base class to change owner trust asynchronously

-   CryptoBackend implementation, connect the progress() and result()
-   signals to suitable slots and then start the job with a call
-   to start(). This call might fail, in which case the ChangeOwnerTrustJob
-   instance will have scheduled it's own destruction with a call to
-   QObject::deleteLater().
-
-   After result() is emitted, the ChangeOwnerTrustJob will schedule it's own
-   destruction by calling QObject::deleteLater().
