Audio rework, new jitter buffer
...
Jitter buffer is now based on packets, not on samples. The frames are
dejittered in received form. After reading from jitter buffer, they are
decoded in correct order. If a frame is missing, it is concealed by
repeating audio.

Refactoring validity check and prefix processing of dialed number
...
Command line help shows how many digits and what prefixes can be dialed.
Giving a station ID via command line will be checked for being valid.
The number to call the mobile statione will be checked for being valid.
Prefixes that are defined for a nework will be removed from station ID
automatically.
Multiple station ID lengths are supported:
* C-Netz: 7 or 8 digits, depending on area code length
* A-Netz: 5 or 7 digits; number is truncated to last 5 digits.
* IMTS/MTS: 5 or 7 digits, depending on phone's selector switch.

This is useful, if SoapySDR supports other SDR devices, like sound card. In
this case "--sdr-device-args driver=lime" must be given at command line. Now
this is done automatically with "--limesdr" or "--limesdr-mini".
