broadcast calls.

Deprecated functions gsm48_generate_mid_from_*() are replaced by
osmo_mobile_identity_encode_msgb(). Clean up code.

VGCS and VBS calls may share the same (call) ref or share with other
protocols. Therefore the MM connection is defined by the reference and
the prococol discriminator.

GCC is the call control for voice group calls, BCC is the call control
for voice broadcast calls.
This patch includes the new message primitives between MM layer and the
GCC/BCC layers.

This allows using well tested standarized API to print, compare, etc. usual
identifiers like PLMN, LAI, etc.
It also simplifies code by avoiding passing lots of parameters and
making it easier to identify which fields go packed together.
This is specially important since in the future more of those
identifiers will be added for GPRS.

In several code paths we put / push structures from 'gsm48_mm.h' into
the message buffers, so then they're unpacked by the message receivers.
The AddressSanitizer complains about unaligned pointer access and
potentially unexpected behaviour. Let's fix this by explicitly
marking those structures as 'packed'.

RR now handles SAPI 3 datalink.
MM connections now have and individual sapi, so MM can use right SAPI
for communication with other layers, as well as releasing the right
MM connections in case of link release.

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.
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.
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.
