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'.

Jenkins build #2516 has uncovered a problem in DATADumpFile.parse_msg():
======================================================================
FAIL: test_parse_empty (test_data_dump.DATADump_Test)
----------------------------------------------------------------------
Traceback (most recent call last):
File "/build/src/target/trx_toolkit/test_data_dump.py",
line 138, in test_parse_empty
self.assertEqual(msg, False)
AssertionError: None != False
I did a quick investigation, and figured out that this failure
happens when trying to call parse_msg() with idx == 0, because
DATADumpFile._seek2msg() basically does nothing in this case
and thus always returns True. The None itself comes from
DATADumpFile._parse_msg().
Let's ensure that DATADumpFile.parse_msg() always returns None,
even if DATADumpFile._seek2msg() fails. Also, update the unit
test, so we always test a wide range of 'idx' values.

Raising exceptions is a Pythonic way to handle errors, which in this
particular case will help us to know *why* exactly a given message
is incorrect or incomplete.

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.

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.
