library/RAN_Emulation.ttcnpp: fix: properly handle SAPI / DLCI for RANAP
Some of our SMS related test cases are failing. The problem is
that SMS related RAN messages shall be sent on SAPI 3, as per
GSM TS 04.11, section 2.3, while they actually being sent on
SAPI 0.
For the messages coming from the TCs towards OsmoMSC over RANAP,
we need to convert from DLCI to SAPI in f_xmit_raw_l3(). OsmoMSC
also needs to be patched, because it seems to ignore SAPI IE.
