Apply new duplication detection logic for M-Notification.ind

The X-Mms-Transaction-ID of the M-Notification.ind identifies each
M-Notification.ind message. New duplication detection logic compares
the new X-Mms-Transaction-ID with the stored value to identify the
Network duplicate M-Notification.ind message when it receives a new
M-Notification.ind message.

Following SQL WHERE clause is used to query from the DB.
 ((m_type=NOTIFICATION_IND) OR (m_type=RETRIEVE_CONF)) AND (exp>NOW))
 AND (t_id=xxxxxx)

For this, when the M-Retrieve.conf is received, updates the t_id and the
exp from the corresponding M-Notification.ind so that new logic would
work even after the M-Notification.ind is deleted.
