Andreas Eversberg a20637825a 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.

Andreas Eversberg c844fcc1f6 If a mobile inscribes, show station ID on the console
If the console's station ID is not set, it will be automatically set
when a call is made from the mobile phone or when it performs
inscription to the network. (Only works for cellular networks with
inscription support.)

Andreas Eversberg 423bc42429 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.
