b32e0ab602 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

743d147d16 SDR: Turn TX power off if requested by network 
The power level is ramped smoothly within 1 ms up or down.

R2000, AMPS and C-Netz turn off power when voice channel is not i use.

C-Netz turns off power between OgK timeslots.

0c9de251be NMT: Implement Hagelbarger Code 
This will correct burst errors of received messages. If the message
is too corrupted, it will be ignored, because some element may not
match then. The digits and line signals are checked for consistency,
since they are repeated serveral times in a message.

7a9762e28e NMT: Disable Supervisory signal during DMS (SMS) transfer and use Timeout 
There is no Supervisory signal during DMS transfer, so there must be
no timeout for Supervisory signal. Instead, the SMS layer will timeout
after some seconds without receiving data.
