re-structure directory tree in preparation of submodules
...
This moves src/lib* to src/lib/lib* so that we can move src/lib
into a submodule in a subsequent commit

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.

A-Netz: Number of operator can be defined now
...
Since A-Netz does not allow automatic dialing, the call is forwarded
to an operator. Use -O <number> to change the default operator's number.

Implementation of RX level squelch (for A-Netz and B-Netz)
...
Use -S <dB> for setting RF level or use -S auto for auto level.
When squelch closes, audio is muted. If squelch is closed for some
seconds (depending on network), call is released. (RF loss condition)
The previous loss detection has been removed

A-Netz / B-Netz: Add function to change state, debug with channel info

Change state uses a function rather than directly setting state
variable.
Some debug commands now use channel number. (for multi-trx setups)

A-Netz: Click removal when changing sequenced paging tones
...
When tone changes to next tone, a transition of 2ms is performed. The last
tone is faded out and the new tone faded in.

A-Netz: Keep phase for each paging tone when played in sequence
...
If paging tones are played in sequence, only one tone out of four tones
is played at once. The phase of all tones are calculated as if each tone
would have been sent permanently.

common: Add pre and de emphasis, if the radio does not support it
...
Connect to the oscillator of the transmitter - good girl!
You need to enable pre emphasis in this case.
Connect to the discriminator of the receiver - good boy!
You need to enable de emphasis in this case.

common code: Add feature to record received audio and replay it
...
-W <file.wav> writes a wave file of received audio
-R <file.wav> reads a wave file to feed into decoder
This way you can record a phone and later debug without a phone
and radio equipment.
