osmo-bsc_nat: Parse MGCP Connection ID as hex
Our ttcn3-bscnat-tests would randomly fail. After the CRCX ACK returns from the MSC the bsc-nat reports it could not find a CI it it and deletes the connection on the BSC-side. This happens because the field is parsed as a decimal value instead of hexadecimal. So a value of 00FED122 is parsed as '0' which is a reserved value in our program. This fix parses the field as hexadecimal value and also logs an error if the value happens to be 0. make check will now test if a hexadecimal CI is parsed correctly. Fixes: OS#3951 Change-Id: I49b8b61644bf706162102dce268cae2265536fc5
