Robert Schmidt 4c7035e6e3 Remove UESIM_EXPANSION 
This completely removes the UESIM_EXPANSION define: it does not compile
at the moment. Its function was to multiplex multiple UEs on the same
TUN interface. However, this functionality is not needed since it is
possible to allocate many TUN devices (i.e., >= 32).

Robert Schmidt a51dc94e8b Set correct UE ID in Kenb Refresh Req 
NAS triggered the Kenb Refresh Req always for (hardcoded) UE 0. This
fixes this by setting the correct UE ID.

An effect of this was that the Kenb would always be set for UE 0,
regardless for which UE it was actually intended. This led for integrity
check failures for every UE with ID > 0.

Cedric Roux cff9149920 fix issue 227 - UE IP settings disrupts realtime 
see https://gitlab.eurecom.fr/oai/openairinterface5g/issues/227

When the UE connects to the eNodeB and receives its IP address from the
network, it calls system() to set it in the linux kernel world. This call
is not done in a realtime thread, but in the NAS, which uses its own thread,
independent of the realtime processing.

In some situations this totally disrupts realtime processing.

It is difficult to know precisely why that happens, but it seems that calling
fork(), as system() does, in a multi-threaded program is not a good idea. (So
say several people on the internet.) It is not clear why the softmodem is
impacted, but it seems that fork() is really what triggers the disruption.
Several tests lead to that conclusion.

To fix the problem, we create a child background process very early in main()
(before anything else basically). Then instead of calling system(), the main
process sends the string to the background process. The background process
gets the string, passes it to system() and reports the success/failure back
to the main process.

This solution involves a lot of system calls, but calling system() in the
first place is not cheap either. As long as no realtime thread uses this
mechanism, things should be fine. Time will tell.
