MSC_Tests.ttcn: introduce TC_gsup_mo_mt_sms_rp_mr 

The idea of this test case is to verify SM-RP-MR assignment for
a few concurrent MO/MT SMS being sent over GSUP.

Basically, the algorythm is the following:

1.0 establish a RAN connection,
1.1 send CM Service Request for MO SMMA indication,
1.2 submit MO SMMA indication on DTAP,
1.3 expect MO-ForwardSM-Req on GSUP,

2.0 send MT SMS using MT-ForwardSM-Req on GSUP,
2.1 expect CP-DATA/RP-DATA for MT SMS on DTAP,

3.0 compare both SM-RP-MR values (for MT, assigned by the MSC),
3.1 send MO-ForwardSM-Res for MO SMMA on GSUP,
3.1.1 expect CP-DATA/RP-ACK for MO SMMA on DTAP,
3.2 send CP-DATA/RP-ACK for MT SMS on DTAP,
3.2.1 expect MT-ForwardSM-Res for MT SMS on GSUP.
