External interface for USSD
As the work on OmsoMSC (#1597) to forward all USSD to the HLR is coming to a conclusion, we now have to create some infrastructure in OsmoHLR to route USSD requests to external USSD entities attached ot OsmoHLR.
There are a number of patches in the
laforge/ussd branch of osmo-hlr.git to implement this. The patches include an example EUSE program.
