The built-in struct module is already used for toa256 decoding,
so let's use it for toa256 encoding, and TDMA frame number
coding too - no need to (re)implement the wheel!

A timeslot can be reconfigured at runtime, this is normal.
We should neither complain nor reject such commands.

False is not iterable, so we should properly handle the case
when parsing of the whole DATA dump was failed (e.g. due to
incorrect offset specified).

This change extends DATAInterface class with new methods:
- recv_raw_data() - read raw data from socket;
- recv_l12trx_msg() - read raw data and parse as L12TRX;
- recv_trx2l1_msg() - read raw data and parse as TRX2L1;
which would simplify the further usage of this class.

It makes much more sense to read data from socket in handle_rx(),
instead of expecting a buffer with received data from caller.

There is no need to (re)define the arguments of UDPLink's constructor.
Let's use non-keyworded variable length argument list (*args).

Since I8fd2a2ab7784b38bde5ebcfd0359b7e2cb53f5a7, SETTA command
handling was broken, because the range limitation was removed
together with argument parsing. Let's fix this.

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.

Both '--bind-addr' and '--burst-type' had the same short '-b'.
Let's use the upper case version for '--burst-type'.

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 randomization of both UL/DL RSSI and ToA values is optional,
and can be configured from the control interface (see both
FAKE_RSSI and FAKE_TOA commands).
The command line options for enabling / disabling the randomization
were redundant, so let's get rid of them and check if the
corresponding treshold value is set.
Change-Id: I6adc13b8989ade2fab895673525c0ca17bf9b3f2
For some reason, the time-slot pass-filtering was only done for
DL bursts, but not for UL bursts. BurstForwarder shall not pass
UL bursts for unconfigured time-slots too.
Let's also print a warning if an UL burst is sent on a not
configured time-slot, i.e. before sending SETSLOT command.
Change-Id: Idb7f5b212e5814aeff8ca8bc875ad066674267cd
Previously it was only possible to configure a single time-slot
that would be pass-filtered by a BurstForwarder instance. In some
applications it would be useful to configure multiple time-slots,
so let's refactor the time-slot pass-filtering algorithm.
Change-Id: Ie1490adaf7a7c62c966aeb60c1898eaf3b5a1e84
Instead of having all configuration variables of BurstForwarder
initialized in the class heading, let's introduce two functions
for initialization (resetting to defaults) of both UL/DL params.
This would allow to reset a BurstForwarder instance from the
control interface in follow-up patches.
Let's also introduce some basic documentation for the class
fields, which were defined in the heading previously.

The idea of SETFH command is to instruct transceiver to enable
frequency hopping mode using the following parameters:
CMD SETFH <HSN> <MAIO> <CH1> <CH2> [... <CHN>]
Note: since the length of a CTRL command is limited to 128
symbols (BTW: why?), the amount of channels is also limited.

Moved to doc/manuals/, with full commit history, in preceding merge commit.
Now incorporate in the build system.
Build with:
$ autoreconf -fi
$ ./configure --enable-manuals
$ make
Shared files from osmo-gsm-manuals.git are found automatically if
- the repository is checked out in ../osmo-gsm-manuals; or
- if it osmo-gsm-manuals was installed with "make install"; or
- OSMO_GSM_MANUALS_DIR is set.

This change revives the main idea of:
Change-Id: I32517567847fd5c54b1742f18bf409ff81e316fa
to stop ignoring the VTY bind address from the config file.
Furthermore, it deprecates (and disables) both 'u' and 'v'
command line options, because they are redundant.
Change-Id: I99e0ec1717edd29b3be231be86616cc7effe5d95
The process should be aborted if a non-existing command line
option or an incorrect parameter value is passed.
Change-Id: Ib656ad12f12429ed15dc2a1554901ffa51148ff6
The VTY requisites are always being printed by libosmovty,
there is no need to duplicate this information.

This reverts commit c8de8cb1e1
(Change-Id I32517567847fd5c54b1742f18bf409ff81e316fa by Max),
because several problems were introduced, in particular:
a) Help message of mobile application is broken:
"The VTY IP to telnet to. (default (null))",
"The VTY port number to telnet to. (default 127.0.0.1)".
b) Default VTY bind addres != parsed from the config file.
c) The (vty_ip == NULL) is resolved only when an external
MNCC handler is used, otherwise NULL is passed to
l23_app_init().
Change-Id: Ic63a4eb828ff32d3744886b4f5f6f5019c798620
Previously the vty bind config parameter was always ignored. Fix this by using proper
default value from the config unless it's explicitly set via command-line parameter.

Log via LOGP() like the rest of the file instead of fprintf() for

Fixes following ASan warning:
git/osmocom-bb/src/host/layer23/src/misc/../common/main.c:146:2: runtime error: null pointer passed as argument 2, which is declared to never be null
The warning however is harmless since in that case, app_len = 0 and thus
size to copy is 0.

Unlike the DATA messages, traffic frames may have different length.
Instead of having fixed payload (i.e. TCH frame) length, let's
introduce a flexible array member. This would allow one to
calculate the frame length using the MSGB API.

L1CTL implementation (i.e. l1ctl.c) is not a good place for the
SIM specific stuff. Let's move it to the proper place (i.e. sim.c).
As a bonus, this change fixes a possible problem of loosing the
cached APDUs if two or more L2&3 applications are using a single
LAPDm connection. The APDU buffer is dedicated per MS now.

Previously the wildcard address (i.e. '0.0.0.0') was hard-coded
as the bind address of TRX interface. Let's make it configurable
by introducing a command line option.
Note that the '--trx-ip' option was deprecated by '--trx-remote',
because it isn't clean whether it is remore or local address. It
still can be used, but was removed from help message.
