MSC_Tests.ttcn: introduce TC_lu_and_ss_session_timeout
The idea of this test case is to verify SS session termination
due to expiry of its guard timeout. The timeout value is
intentionally set to a few seconds in order to speedup
test case execution (we don't want to wait 2 minutes).
We expect OsmoMSC to inform both session entities (MS and EUSE)
about timeout expiry before releasing the transaction. The MS
should receive GSM 04.80 RELEASE COMPLETE message with optional
cause, while the EUSE should receive OSMO_GSUP_MSGT_PROC_SS_ERROR.
At the moment, it's not clean which cause values should be used:
- for GSM 04.80 RELEASE COMPLETE the cause IE is optional,
and possible values are defined in GSM TS 04.08, annex G-H.
The H.6.7 Cause No. 102 "recovery on timer expiry" seems to
be suitable;
- for OSMO_GSUP_MSGT_PROC_SS_ERROR the generic cause IE could
be used, but actually this IE is not generic at all, and
limited by 'gsm48_gmm_cause' enum;
so we temporarily expect arbitrary cause values in both messages.
