c2f14834e5 Rename dbm0 (level) to speech (level) 
In mobile communications we use speech level instead of milliwatts.
The deviation (FM) is always based on speech level, not on 1 milliwatt.

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.

7e45f556ce Correcting all levels and move all remaining integer samples to sample_t 
The leves are based on the standards of each mobile network. They
are adjusted to the specified frequency deviation now.
