Andreas Eversberg 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.

Andreas Eversberg 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.

Andreas Eversberg 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.

Andreas Eversberg 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.

Andreas Eversberg 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.

Andreas Eversberg 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

 * --limesdr allows to auto-set required SDR option for LimeSDR
