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.

9ff8c3bb25 Rework on audio interface 
Sound instance is now called audio instance and uses funcation pointers.
This gives a clean interface to be exchanged with other technologies,
linke SDR.

e724823c5b A-Netz: Reset tone detector when going idle 
A pending tone must be detected as soon as the cell is idle. This happens
if the phone picks up during release guard time.

481181fa74 A-Netz: Click removal when changing sequenced paging tones 
When tone changes to next tone, a transition of 2ms is performed. The last
tone is faded out and the new tone faded in.

52b1ac65f4 A-Netz: Keep phase for each paging tone when played in sequence 
If paging tones are played in sequence, only one tone out of four tones
is played at once. The phase of all tones are calculated as if each tone
would have been sent permanently.

8d7c7f4425 callref: Move callref from 'sender' to individual implementation of a, b, c-netz 
Cellular networks use transaction instances, so callref is now member of
transaction object.
