Remove the paragraph about writing to the Free Software Foundation's
mailing address. The FSF has changed addresses in the past, and may do
so again. In 2021 this is not useful, let's rather have a bit less
boilerplate at the start of source files.

I intentionally do not use 'Downlink' and 'Uplink' terms in this project
because both MS and BTS transmit and receive on the opposite directions.
A burst coming from demodulator may be a Downlink or an Uplink burst
depending on the context, so we definitely need more precise terms.
Back then when I started to work on TRX toolkit, I decided to use the
'TRX2L1' and 'L12TRX' for receive and transmit directions respectively.
Now I find them hard to read, so let's replace them with 'Rx' and 'Tx'.

Since version 3.8, Python warnins us that using the "is" and "is not"
operators with string and numerical literals is a bad idea. Let's
avoid this and use the classical '==' and '!=' operators instead.

For sure, the following message is much more informative:
Ignoring an incorrect message: Unhandled version 12
than:
Failed to parse message, dropping...
NOTE: since the way of printing exceptions is different in both
Python versions, I had to drop Python 2 support.

Since we have introduced ApplicationBase class, that are used
by all existing applications, let's merge the copyright
printing helper into it.

Before this change, it was impossible to configure logging
parameters from command line, such as log level and format.
This change introduces the following optional arguments:
--log-level - logging level for stderr (by default, DEBUG);
--log-format - logging message format for stderr;
--log-file-name - enable logging to a given file;
--log-file-level - logging level for file (by default, DEBUG);
--log-file-format - logging message format for file;
which are defined in a new class called ApplicationBase, so
all existing applications should inherit them now.

There are multiple advantages of using Python's logging module:
- advanced message formatting (file name, line number, etc.),
- multiple logging targets (e.g. stderr, file, socket),
- logging levels (e.g. DEBUG, INFO, ERROR),
- the pythonic way ;)
so, let's replace multiple print() calls by logging calls,
add use the following logging message format by default:
[%(levelname)s] %(filename)s:%(lineno)d %(message)s
Examples:
[INFO] ctrl_if_bts.py:57 Starting transceiver...
[DEBUG] clck_gen.py:87 IND CLOCK 26826
[DEBUG] ctrl_if_bts.py:71 Recv POWEROFF cmd
[INFO] ctrl_if_bts.py:73 Stopping transceiver...
[INFO] fake_trx.py:127 Shutting down...
Please note that there is no way to filter messages by logging
level yet. This is to be introduced soon, together with argparse.

The Scapy itself was the actual cause of continuously growing
memory consumption. It was configured to store the captured
packets, what isn't required for this tool.

This toolkit has branched out into several different tools for
TRX interface hacking, and creating a virtual Um-interface
(FakeTRX) is only one of its potential applications.
