Neels Hofmeyr c47ce855c1 msc: detect RTP to CN failure in call tests When CN RTP is missing, the X2 timer will fire after all other call signalling looks successful. So far we establish an MT call, wait three seconds and directly disconnect, long before X2 or X2427 can fire. Make X2 shorter. (By means of f_vty_config() from ttcn, so that we don't need to edit various osmo-msc.cfg in various repositories. The short timer is always critical for the test to be accurate.) Add proper function to detect premature disconnect. Otherwise we just get a cryptic message like "Couldn't find MnccExpect for incoming call" because of MNCC messaging after the unexpected release event.
