Add btd_request_authorization_cable_configured() function to allow
cable configured devices to ask the user straight away about whether the
device should be allowed to connect to the computer.
This allows us to ask the user at the time of the USB connection and
initial setup, rather than when the first Bluetooth connection is made.
The fact that the device might not be connected to the adapter when
this event is triggered is mentioned in the Agent API docs.
