allocation.

Robert Schmidt 9d2651d080 CI: Parse UE TUN interface correctly in S1 mode 
See also commit 8c5976e279

Above commit changed the TUN interface configuration to use program "ip"
only. This commit changes the CI script parsing correspondingly: the
pipeline will recognize the attempt to bring up the interface of the
first UE.

Robert Schmidt 8c5976e279 Use "ip add" to add IP addresses 
This then only uses the "modern" ip tool instead of ifconfig, and the
command is more "homogeneous".

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 9882460607 Remove Mutexes in phy_stub_UE.c 
Various mutexes are present in the phy_stub_UE.c file. However, it will
only be run in a single thread; the multiple-thread implementation also
runs the higher layers concurrently, which leads to races and segfaults.
Therefore, remove these mutexes, as we don't need them.
