Add option to cross-connect calls; Calls between mobiles are now possible
...
Use -x to enable call cross-connect. No MNCC socket, no call device must
be specified!
Be sure to have at least one control channel and two voice channels.
Alternatively you can use one combined control/voice channel and one
voice channel.

Implementation of RX level squelch (for A-Netz and B-Netz)
...
Use -S <dB> for setting RF level or use -S auto for auto level.
When squelch closes, audio is muted. If squelch is closed for some
seconds (depending on network), call is released. (RF loss condition)
The previous loss detection has been removed

This drastically increases the signal-noise-ratio and removes co-channel
interferences. It gains CPU usage, but only on SDR threads, not on the
main thread.
