Added sequence number to L3 messages (see GSM 04.08 Clause 3.1.4.3)
This is required to detect duplicated messages during assignment or
handover. Each PDISC uses its own sequence number, but MM+CC+SS share the
same. The sequence number is only required in uplink direction.
Dieter: Please check, if your tester eats it now. Also try to trace if the
sequence number is set correctly.
