Since we have two ways to interact with a physical SIM:
- using built-in SIM reader of the L1 PHY (via L1CTL),
- using remote reader via (BT)SAP protocol,
name 'GSM_SIM_TYPE_READER' looks quite confusing. Let's rename it
in order to explicitly indicate the role of L1 PHY.

When starting multiple mobile in the same second, the libc random number
generator will be seeded to exactly the same value.
The random bits inside the RACH request(s) will be exactly the same
across multiple mobile and when the channel fails they all pick the same
randomized back-off timing.
Use stronger random numbers and replace all calls to random(2) with
osmo_get_rand_id. Add a fallback to try random().
[v2: Add helper to make sure the result is int and between 0 and
RAND_MAX]

It was decided to migrate to osmo_get_rand_id() and use random()
as a fall-back. But there is a critical difference between both
functions: osmo_get_rand_id() fills an input buffer with random
bytes (0x00 - 0xff), while *random() returns a value in range
between 0 and RAND_MAX.
osmo_get_rand_id() was used in a wrong way, so in some cases we
could get a negative value (how about IMEI starting from '-'?),
what isn't expected in many cases and could lead to unexpected
behaviour and segmentation faults...
This reverts commit 6d49b049ee304f1ea0e4801df61e69713b01f0f8.

Disable storing the SMS on disk. This is useful when scripting mobile.
Keep the default of attempting to store it to disk.

When no cell was found during the PLMN search the camp on any cell
state will be entered. LUs are prevented in this state and it will be
left after the start_any_timer has timedout. Even if camping on the
home network the state will not be left before the expiry of the timer.
For systematic tests this is producing a too high upper bound. Make it
configurable so we can succeed with a UL more quickly.

Right now the script will be executed once it is loaded. Make sure
to write it into the config file last. Expose various log commands
for logging. Jump through some hoops and get the filename and line
number from lua.

All levels in range of 0..63 are now uint8_t and use "rxlev" as
variable name. All levels in range of -110..-47 are now int8_t and use
"rxlev_dbm" as variable name.

If there is no SIM card in the reader, the SIM process would
automatically proceed without SIM anyway.

This patch introduces cell re-relection. When camping on a cell, it
scanns neighbour cells. If a 'better' cell is found, the cell is selected.
If the cell is in a different location area, a location upating is
performed under certain conditions.
The 'better' cell depends on various informations that are broadcasted on
the BCCH of a neihbour cell and of course the RX level. Most operators
don't set these informations, so the 'better' cell depend on a better
RX level for the same location area, or a much better RX level (6 dBm)
at a different location area.
There were many issues at the idle mode process that has been fixed.
Expecially when moving, the state machines got stuck, so no more cell search
was possible, or no further calls / location updating was possible.
In order to see the process of cell selection, enter the VTY interface and
enable the network monitor:
enable
monitor network 1 (where '1' is the instance of the MS)
In order to see the current state of the processes, enter:
show ms

This makes it possible to use GSM 850 and PCS 1900 bands, as used in the
US. The support relies on the phone hardware.
Each band (900, DCS, 850, PCS, 480 and 450) can be enabled and
disabled individually for each setting.

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.

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.

It is possible to store phone numbers with abbreviations now. Dialing these
abbreviation makes testing of mobile originated calls much easier too.

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.

Supported features of hardware (support.c) can be disabled by config.
This way the full featured mobile can be downgraded to indicate less
features to the network, like disabling speech support or crypto support.
|
|
The default (if config not yet created/updated), is still taken from
settings.c.

This split the headers and adapt the source.
We use osmocom/bb as a prefix because libosomore also
uses osmocom and generic names such as misc & common could
conflict in the future.
