Robert Schmidt b389e43eea Add phytest preprocessor 
The phytest preprocessor schedules only one UE, as many RBs as possible
(largest continuous RB region), with a fixed MCS and time domain
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.

lock does not happen.

Robert Schmidt e956c17bf8 Rename NR_UE_list_t to NR_UE_info_t 
The name NR_UE_list_t is misleading: beyond being a simple "list", this
structure carries all/most UE-related MAC information. If at all, it is
a container for multiple lists. The next commit introduces a
NR_UE_list_t structure that organizes UEs in lists such that it is
easier to go through the UEs.

Robert Schmidt de2cf2393b Do not allocate CCE in nr_configure_pdcch() 
nr_configure_pdcch() allocates the CCE, but this is not wanted, e.g., in
multi-user scheduling, since it might not be possible to allocate the
CCEs for these UEs. This commit makes the following changes:

- remove CCE allocation in nr_configure_pdcch()
- remove coreset search in nr_configure_pdcch()
- add functions get_coreset() and get_searchspace() to retrieve coresets
  and search spaces easily
- in nr_fill_nfapi_dl_pdu(), add extra parameters for aggregation level
  and CCE indices and the searchspace and coreset of a UE, which might
  be different for each UE
- allocate CCEs manually in phytest, RA, and DLSCH schedulers
