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.

Previous hardcoded default of 0.0.0.0 was inappropiate in some
scenarios, as it sets the SRC addr of the packets sent through the
socket based on the routing.
For instance, if iface IF1 has assigned two IP addresses A and B,
A being the first addr of the interface, and osmo-bts-trx is
configured with "osmotrx ip local A" and "osmotrx ip remote B",
the following happens:
CMD POWER OFF src=A:5801 dst=B:5701
RSP POWER OFF src=A:5701 dst=A:5701 <-- A is assigned as src addr.
But osmo-bts-trx is waiting for packets from B:5701, and the packet
is dropped with ICMP Unreachable. If addr binding is forced in
fake_trx to B, then everthing's fine.
Let's extend the UDPLink in order to allow manual, but optional
setting of bind address, and add a corresponding cmdline
argument to all executables.

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.
