obexd: Automatically setup notification connection for MAP client

This automatically establishes the MNS connection when the MAS client
session is started and terminates the MNS connection when the MAS client
session is closed.

The MAP client controls the notification channel using the
SetNotificationRegistration function. The MSE will connect/disconnect
the MNS connection accordingly.
