Change subject: GSUP/SMS: introduce READY-FOR-SM message and IEs
......................................................................
GSUP/SMS: introduce READY-FOR-SM message and IEs
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' which is replicated as OSMO_GSUP_SM_AL_REAS_IE.
