libmsc/gsm_09_11.c: forward SS/USSD messages to HLR over GSUP
In order to be able to support external SS/USSD gateway, we should
not terminate the GSM 04.80 messages at OsmoMSC. Instead, we need
to follow the GSM TS 09.11 specification, and forward all messages
unhandled by OsmoMSC to OsmoHLR over GSUP protocol.
This change implements forwarding of MO SS/USSD messages. The
forwarding assumes transcoding between GSM 04.80 messages and
GSUP messages. The payload of Facility IE is carried 'as is'.
As a side-effect, this will disable the osmo-msc internal handler
implementing the "*#100#" for obtaining the subscribers own phone
number. In order to re-gain this functionality, you will need a
modern osmo-hlr (Change-Id I1d09fab810a6bb9ab02904de72dbc9e8a414f9f9)
and the following line in your osmo-hlr.cfg:
hlr
ussd route prefix *#100# internal own-msisdn
TTCN-3 test case: I01de73aced6057328a121577a5a83bc2615fb2d4
