src/hlr.c: resolve/scramble pseudo IMSI in GSUP
Resolve the pseudonymous IMSI to the real IMSI as soon as possible, when
a GSUP message arrives. Use the real IMSI internally in OsmoHLR, so the
existing logic does not need to be changed. Scramble the IMSI back to the
pseudonymous IMSI in one common place (gsup_server_send_req_response)
right before responding to GSUP messages.
