xua_snm: Implement handling of DUPU messages
A DUPU message in SUA and M3UA indicates the unavailability of
a (MTP-level) user, i.e. the entire SCCP, ISUP, ... is not available.
If we receive a DUPU (destination user part unavailable) message in ASP
role, then we must
* distribute it to any other ASPs for which we operate in SG mode
* pass it as MTP-STATUS.ind to SCCP, which can then generates
N-PCSTATE.ind to the SCCP User
