4cd9cb787e C-Netz: --ms-power defines power level (not P-bits) 
Also the level 8 can be selected. Actually level 6 is selected, but
reduced to 8 when making a call.

c2f14834e5 Rename dbm0 (level) to speech (level) 
In mobile communications we use speech level instead of milliwatts.
The deviation (FM) is always based on speech level, not on 1 milliwatt.

360729d270 C-Netz: Added list of base station names and IDs 
Automatic polarity detection is now done by using the polarity of last
transmitted message. We cannot use two base station IDs anymore, to
detect the polarity. Now we deal only with the defined base station ID.

195f7481d8 C-Netz: Correctly synchronize time stamp of SpK to OgK 
Even if the SpK is not used (yet), it must count time stamp (bit_time) so that
SpK keeps in sync with the OgK, until frames are received from mobile station.

13245c56f6 C-Netz: Add authentication support (process only) 
No real authentication, since the algorithm and the keys inside the cards
are not known. A challenge can be specified and optionally the response
can be verified.

e4314749fd Fixup for fast mathm 
Because users of libfm do always call fm_init and fm_exit, it must be
included in every build.

3b81007210 Refactoring command line option handling 
* Use own function to define and parse command line options

 * Command line options can be defined by config file also

b32e0ab602 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
