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.

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.

f3fd01ebcd ALSA code: Fixed corrupted sample at the end of a read 
The last sample may get corrupted. It seems that this depends on the
card that is used. To fix this, the snd_pcm_avail is checked and
one sample less than available is read using snd_pcm_readi. This
sample remains in RX buffer until next read. Then it is not corrupted.
