Piotr Krysik db65883a68 apps/grgsm_trx: remove redundant unit from freq_offset variable name 
Frequency is always in Hz so there is no need to add that
information in the variable name.

Piotr Krysik d6e8bb744e apps/grgsm_trx: remove unnecessary checks of freq_offset 
Checking if freq_offset is None doesn't make sense currently
as it's always set to a float value by argparse (to 0 by default).

Piotr Krysik fcb64a8adf grgsm_trx: Migrated argument parsing to argparse 
Argparse makes adding new parameters easier and
adds consistent way of handling default values of
parameters and printing of their help info.

Vadim Yanitskiy 3f9abbdf92 apps/grgsm_trx: add baseband frequency shift feature 
An ability to shift the baseband frequency would allow one to
run both base stations and (OsmocomBB-based) mobile stations on
any frequency (e.g. in 2.4 GHz WiFi band)!

This is achieved by adding a given frequency offset to the
result of "ARFCN -> RX/TX frequency" calculation.

Usage example:

  grgsm_trx --freq-offset -500M

Both RX (Downlink) and TX (Uplink) frequencies will be shifted
by 500 MHz back, e.g. tuning request to ARFCN 105 would result
in tuning the radio to 456.0 MHz (instead of 956.0 MHz).

Vadim Yanitskiy 216558454d apps/grgsm_trx: introduce bind address option 
The new option (-b --bind-addr) allows one to specify the bind
address for both DATA and CTRL interfaces. By default, '0.0.0.0'
is used, so there are no restrictions for the L1 source address.

Vadim Yanitskiy f94a51b64d gsm_trx_burst_if: allow to customize the bind address 
Pleviously remote address for DATA interface was also used as the
bind address, what is definitely wrong. Let's change the API a bit
in order to allow one to specify a custom bind address.

Vadim Yanitskiy 45457e959d trx/radio_if.py: reset UHD device time at startup 
Some UHD devices, such as UmTRX, require one to manually reset the
hardware clock, otherwise the burst transmission doesn't work.

Vadim Yanitskiy d222ee58bb trx/radio_if.py: implement AFC for both RX and TX paths 
AFC (Automatic Frequency Control) was previously only utilized in
the receive path of the radio interface. Now we also need to keep
the transmitter frequency as accurate as possible.
