When gr-osmosdr is compiled with SoapySDR support and SoapyAudio is
installed the audio device is picked as a first choice when detecting
devices but grgsm tools are not able to work with audio devices. So in
such cases the user has to always specify the correct SDR device in the
args parameter which is a bit inconvenient.
When args is not specified call osmosdr.device_find to get all devices
and filter out unspported ones like SoapyAudio devices. When args is
specifed just try to create osmosdr.source with whatever value has been
specified.
Add -l and --list-devices command line option that prints information
about all detected devices.
Example commands:
grgsm_capture --list-devices
grgsm_capture --list-devices --args=nofake
grgsm_capture --args=uhd,type=b210 -a 111 capture.cfile
grgsm_livemon --args=rtl
grgsm_livemon --args=uhd,type=b210

We need a space between numchan=1 and the rest of the device arguments
otherwise when --args is specified it fails with RuntimeError: bad lexical cast
$ grgsm_capture --args=soapy

grmgs_capture tried to do too many things for a simple recorder.
It was simplified by removing the receiver and ability to
save data to bursts files.
All other stuff that is not necessary for recording signal to disk was
also removed:
-setters/getters,
-storing of parameters that never will be changed.
The 'fc' parameter name was changed to 'freq' to follow GNU Radio
guidelines.
The 'shiftoff' parameter was removed.
'bb_gain' and 'if_gain' parameters were added.
Variables specific to some of SDR's like:
-gains at different stages,
-bandwidth (not all devices can set it),
-antennas (some devices have just one, some not),
were moved to separate options group.
What is left to be exposed is:
-dc_offset_mode,
-iq_balance_mode,
-gain_mode.

The install target install some binaries without language extentions and
others with such extension:
* grgsm_capture.py
* grgsm_channelize.py
* grgsm_decode
* grgsm_livemon
* grgsm_scanner
It would be more consistent and according to the policy of Debian and
Ubuntu if all the binaries were without such language extention. This
commit rename grgsm_capture.py and grgsm_channelize.py to avoid the
language extention.
