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.
Revert "grgsm_livemon: Set cell_allocation to [0]"
This reverts commit 013d4c258c6ad31c2581f0caa4eee3aa609fd9de.

And currently grgsm, gr-osmosdr and gr-iqbal are installed in
/usr/local/lib/python3/dist-packages/ which is not in the default python
search path.

For some yet unknown reasons in travis on Debian testing and Kali rolling
the message gets printed after the burst and decode.sh and decrypt.sh
tests fails because of this.
Instead of filtering this messages in the tests I think it is better
such messages to be printed on the standard error output

- 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

- Change "6,90 kbit/s" to "5.9 kbit/s"
A typo reported in github ptrkrysik/gr-gsm#456
- Comment out the "Error! frame_nr:" message as it turns out to confuse
users more then it actually helps debugging.
- When voice-boundary detection is enabled write the name of decoded
control channel messages

- 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

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.

In the GSM input adaptor and GSM Receiver blocks the osr was hardcoded

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
