Bluetooth: Add skeleton for handling disconnect complete events

Browse source 
This patch adds a simple event handler for the LE Disconnection
Complete HCI event. An extra thing the handler needs to do is to
re-enable advertising if necessary, since it will have been implicitly
disabled by the controller upon a connection event.
