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.

3788b3e8a5 TACS support (variations added to AMPS code) 
These are:

- Bandwidth only 25 KHz, so lower deviations
- Data rate only 8000 KHz
- SID is called AID (Area ID)
- MIN1 coding is different

57d4d1739e AMPS/C-Netz: Correctly release pending transaction when creating a new one 
If transactions is created, look on all channels for pending transaction
with same subscriber.

1. Remove that transaction.

2. Make channel return to IDLE.

3. Release call, if callref exists.

bb64c6b3ba AMPS: Add DTX support 
When DTX is enabled (-S dtx=2 or 3), a missing SAT tone causes the receiver
to mute audio and insert a low level of comfort noise.
Also the missing SAT tone will not cause the connection to be terminated.

438ce08add SoapySDR support

synchronous to received RX rate.

8b9277615d Neu structure for the paging process (B-Netz) 
Paging tones are not created within sound_alsa.c
The audio API is now responsible to switch to paging channel.
In case of SDR, the sdr.c will switch frequency offset.
