This patch changes include paths to get osmocom-bb working with
the current libosmocore tree.
Among all these renames, you can notice several tweaks that I
added on purpose, and that require some explanation, they are:
* hexdump() in osmocon.c and osmoload.c has been renamed to avoid
clashing with hexdump() defined in libosmocore.
* gsmmap now depends on libosmogsm. Actually I had to cleanup
Makefile.am because I was experiencing weird linking problems,
probably due to a bug in the autotools. With the change included
in this patch, I got it compiled and linked here correctly.
This patch has been tested with the phone Motorola C123 and the
following images files:
* firmware/board/compal_e88/hello_world.compalram.bin
* firmware/board/compal_e88/layer1.compalram.bin
Using the osmocon, bcch_scan and mobile tools.

Be able to add extra (short) options from the 'applet' to
the main application. Use this to print the help mentioning
app specific options, pass the getopt string and handle the
command line parsing for it.
Change cell_log to keep the logname in the app_cell_log.c
and then access it from the cell_log.c implementation.
Make it possible that each l23 app can inject the copyright string,
also prepare to have callbacks for the config handling and other
places. This will be useful to add app specific config options.
connect's addrlen should be sizeof(local), not the contained path's length.
With the previous code, on OS X connect() will fail with ENOENT.
This permits layer23 to work on OS X using the pl2303 driver,
/dev/tty.usbserial , MacPorts arm-elf-gcc and RANLIB=arm-elf-ranlib

To create another instance: 'ms <name> create'
To remove an instance: 'no ms <name>'
If no instance exists, 'ms 1' is created automatically on startup.
Each instance can be enabled / disabled by using 'shutdown' or
'no shutdown'. Multiple instances may share the same layer2 socket (same
phone hardware), but in this case only one instance can be enabled at the
same time. This makes it much easier to select different settings without
modifying them.
A 'shutdown' initiates the IMSI detach procedure before shutdown is
completed. A 'shutdown force' will immidiately shutdown.
There is no need to restart the software anymore, if fundamental settings
are changed. In this case, a 'shutdown' followed by a 'no shutdown' will
do the job.
If you already have an old osmocom.cfg, you need to "no shutdown" it.
Everything else behaves as before.
Sylvain found out that the state was not cleared when receiving an RR
response with F-bit == 1. The missing handling is now added and tested.
Furthermore there is a minor fix to prevent underflow when resending last
frame in "timer recovery state".
In order to resume correctly, the first message (ASSIGNMENT COMPLETE or
HANDOVER COMPLETE) must be sent after the link is resumed. Therefore it
must be given with the resume command. Unacknowledged messages are
transmitted afterwards, if any.
There are two criterions for lossing a signal, idle mode and dedicated mode.
A counter counts down when a frame is dropped, and counts up when a valid
frame is received on certain channel. The loss criterion is reached, if the
counter reaches 0. The values added to / removed from the counter and the
limits depend on the process.
This is a quick workarround to make synchronizing to a cell more reliable.
Without it, just a few cells will sync. When network search is restarted, no
more sync happens. By increasing the freq_err_thresh1 to 10000, many cells
sync, even after the first network search.
The cell provides SYSTEM INFORMATION 5* and 6. These are used to create a
list of neighbor cells to monitor. Because there is no neighbor cell
monitoring supported by layer1, the list has no valid results yet.
Currently the average RX level of received frames are used to generate a new
report every second. The report is transmitted to layer1 and used there
whenever a measurement report has to be transmitted.
The timing advance and the current transmit power (as requested by network),
is included with every report.
Optionally RSL_IE_ACCESS_DELAY and RSL_IE_MS_POWER can be given with a
message. They will be used to fill the first two bytes of the SACCH uplink
frame. The format equals to the UNIT DATA indication.
The tx queue was not flused in case the SABM timer fired, so there were old
frames (SABM) still in the queue after next establish request.
Because the problem was solved, debugging code ist removed.
The SIM client is now complete. Because it usefull for multiple
applications, i moved it to the layer23/src/common directory.
The SIM reader works together with mobile process. Fixes were made.
Thanx to all for testing, finding bugs, and making it work as it is
supposed to do.
The current version uses special L1CTL messages to send and receive APDUs.
This will change in the future, when BTSAP interface is completed.
Please note that this client will not work until the layer1 SIM reader
fixes and extensions are committed.
