As the directory structure in the repository is different then the one
after the package gets installed we need to add those subdirectories to
the __path__ otherwise python3 is not able to load the modules using the
relative import syntax and grcc compilation and some unit tests fail.
Mofiy __path__ only when the CMAKE_BINARY_DIR environment variable is
present.

- Use relative import for grgsm's modules
- Convert map to list
- Remove the hier_block.py workaround as as gnuradio 3.7 is no longer
supported in this branch

Add support for RACH bursts although they are not yet supported in the
receiver and control channel decoder blocks.

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

- The second argument of tch_h_decoder constructor is a string that
accepts the value of MultiRate configuration element and not an enum
like the tch_f_decoder decoder.
- Make the demapper's burst sink required.
- Make all parameters visible.
- Rename the TCH/H Channel parameter to Sub-channel number.
- Add the qa_tch_h_decoder test in the CMakeLists.txt
- Fix several typos

The old name was quite long, resulting into cumbersome imports:
from change_sign_of_dict_elements import change_sign_of_dict_elements
let's use a shorter variant:
from dict_toggle_sign import dict_toggle_sign

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).

- Read bursts with pmt::deserialize directly from the std::filebuf
- Remove the unused unserialized variable
- Add tests
Since df978693 when the rx_time tags are present in the incomming stream
the gsm receiver adds fm_time to the burst's PMT and the bursts that
burst file sink writes becomes longer because of the additional field.
The burst file source block was expecting all burst to be 147 bytes long
and reading files with longer bursts was failing with an unhandled exception.

Argparse makes adding new parameters easier and
adds consistent way of handling default values of
parameters and printing of their help info.

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).

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.

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.

When we receive a control command, we should not simply send the
response to the default destination, but send it back to the exact
IP/prt from which the command originated.
This ensures correct routing of responses even in case multiple
programs are interfacing concurrently with a control socket.

Setting this option allows one to reuse existing connections,
for example, by injecting CTRL commands or DATA bursts
into existing connections.
