* for which remotely provisioned keys should be managed.
* @param callback Receives the result of the call. A callback must only
* be used with one {@code getRegistration} call at a time.
*
* Notes:
* - This function will attempt to get the service named by irpcName. This
* implies that a lazy/dynamic aidl service will be instantiated, and this
* function blocks until the service is up. Upon return, any binder tokens
* are dropped, allowing the lazy/dynamic service to shutdown.
* - The created registration object is unique per caller. If two different
* UIDs call getRegistration with the same irpcName, they will receive
* different registrations. This prevents two different applications from
* being able to see the same keys.
* - This function is idempotent per calling UID. Additional calls to
* getRegistration with the same parameters, from the same caller, will have
* no side effects.
* - A callback may only be associated with one getRegistration call at a time.
* If the callback is used multiple times, this API will return an error.
