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.

fda224c27f Fixing and improving SDR support (SoapySDR and UHD)
- Soapy SDR now works.
- Channels can be selected.
- Antennas can be listed and selected.
- Device args, tune args, stream args can be specified.

4201717f36 Rework on audio buffer management
Use function to get samples to be sent to fill audio buffers to a
level. This replaces the function that only shows how much data
is in the buffer.

This way the function itself can control how much data will be
sent.

2e1999b1ee Start streaming of sound/SDR just before main loop
This prevents buffer overflow during init/creation processes

438ce08add SoapySDR support
There is no time stamp handling. It is just TX'ing in advance and
synchronous to received RX rate.

7ea3bc188d Move samples of int16_t format to sample_t, that is of type double
This prepares the correction of all levels

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.
