SDP is added to the MNCC protocol in osmo-msc
Ie16f0804c4d99760cd4a0c544d0889b6313eebb7.
This patch adds SDP to the ttcn3 MNCC messaging.
These changes still work with current osmo-msc master that doesn't send SDP /
ignores received SDP in MNCC.

The MNCC Unix Domain Socket encoding uses an int here, which is
a bit odd, given that it's an ASCII / IA5 char value on the actual
GSM L3. Let's convert from/to something useful.
