  app_voicemail: Voicemail callback registration/unregistration function improvements.

  * The voicemail registration/unregistration functions now take a struct of
  callbacks instead of a lengthy parameter list of callbacks.

  * The voicemail registration/unregistration functions now prevent a
  competing module from interfering with an already registered callback
  supplying module.
