Both session state and session ID IEs were left from the initial
version of Ibe325c64ae2d6c626b232533bb4cbc65fc2b5d71. There is
no need to use them (as we use SM-RP-MR), so let's clean up.

Implement necessary messages for Procedure Check_IMEI_VLR (TS 23.018
Chapter 7.1.2.9). This lets the VLR ask the EIR to check if an IMEI
is valid. In the Osmocom stack, we don't have an EIR and this request
will be handled by the HLR. We will be able to store the IMEI in the
HLR as side-effect (OS#2541).
This is roughly based on TS 29.002 8.7.1 MAP_CHECK_IMEI service, but
only implements the bare minimum required IEs (imei and imei_result).

According to 3GPP TS 29.002, section 12.4, MAP-READY-FOR-SM is
used between the MSC and VLR as well as between the VLR and the
HLR to indicate that a subscriber has memory available for SMS.
This change replicates this service in GSUP as READY_FOR_SM_*.
The only mandatory IE for this service (excluding Invoke ID) is
'Alert Reason' that is replicated by OSMO_GSUP_SM_ALERT_RSN_IE.

According to 3GPP TS 29.002, there are two services:
- MAP-MO-FORWARD-SHORT-MESSAGE (see 12.2),
- MAP-MT-FORWARD-SHORT-MESSAGE (see 12.9),
which are used to forward MO/MT short messages.
This change replicates both services as GSUP messages:
- OSMO_GSUP_MSGT_MO_FORWARD_SM_*,
- OSMO_GSUP_MSGT_MT_FORWARD_SM_*.
Please note, that only the 'must-have' IEs are introduced
by this change, in particular the following:
- OSMO_GSUP_SM_RP_MR_IE (see note below),
- OSMO_GSUP_SM_RP_DA_IE (see 7.6.8.1),
- OSMO_GSUP_SM_RP_OA_IE (see 7.6.8.2),
- OSMO_GSUP_SM_RP_UI_IE (see 7.6.8.4),
- OSMO_GSUP_SM_RP_MMS_IE (see 7.6.8.7),
- OSMO_GSUP_SM_RP_CAUSE_IE (see GSM TS 04.11, 8.2.5.4),
where both SM_RP_DA and SM_RP_OA IEs basically contain
a single nested TV of the following format:
- T: identity type (see 'osmo_gsup_sms_sm_rp_oda_t'),
- V: encoded identity itself (optional).
According to GSM TS 04.11, every single message on the SM-RL has
an unique message reference (see 8.2.3), that is used to link
an RP-ACK or RP-ERROR message to the associated (preceding)
RP-DATA or RP-SMMA message transfer attempt.
In case of TCAP/MAP, this message reference is being mapped to the
Invoke ID. But since GSUP has no 'Invoke ID' IE, and it is not
required for other applications (other than SMS), this change
introduces a special 'SM_RP_MR' IE that doesn't exist in MAP.

In order to be able to transfer SS/USSD messages via GSUP,
this change introduces the following new message types:
- OSMO_GSUP_MSGT_PROC_SS_*,
and the following new IE:
- OSMO_GSUP_SS_INFO_IE
which represents an ASN.1 encoded MAP payload coming to/from
the mobile station 'as is', without any transcoding.

Unlike TCAP/MAP, GSUP is just a transport layer without the
dialogue/context. This prevents us from having session based
communication, required e.g. for USSD. But we can emulate
TCAP dialogue by adding additional IEs, which would allow
to relate each message to a particular session.
This change introduces the following IEs:
- OSMO_GSUP_SESSION_ID_IE,
- OSMO_GSUP_SESSION_STATE_IE,
which optionally can be used to indicate that the message is
related to a session with given ID, and to manage session
state, i.e. initiate, continue, and finish.

These fields can be in the ISD and the PDP Context inofmration. Store
pointers to this IE in both cases. It needs to be used by the SGSN
when opening a PDP context.

Configure logging to be deterministic and add stderr checking to testuite.at.
However, exclude the thousands of message modification log lines from the log
to not have a huge test expectation file.
