Different threads (e.g., RRC, DU tasks) might access the scheduler at
the same time as the thread that drivers the scheduler itself
(ru_thread). To avoid data races, introduce this mutex.
Most functions of the scheduler are only used internally and have been
marked static in the previous commit. The remaining ones, in this
commit, either lock the scheduler mutex sched_lock, or a comment has
been added of the assumption of how such function is to be locked (e.g.,
if it might be called from different places, or if it is called by a
function that already locks the scheduler).
To know which functions are used from outside and which are
module-local, make many functions static. This will allow us to protect
only those functions with a mutex for which it is necessary.
The CellGroupConfig should come from the DU. Currently, any update made
to the CellGroupConfig is done at CU. In split-operation, we have no way
of telling the DU about this update. Hence, in this commit, check if we
are in F1 split mode operation during a CellGroupConfig update, and if
so, suppress any updates to the CellGroupConfig, alongside a warning.

Add Dockerfile, OpenShift build config, and OpenShift image stream, to
compile OAI using clang, notably to get compiler warnings and keep it
OAI compilable using clang.
clang (at least version 14.0.6 used on the cluster) is very slow when
compiling both ASan and UBSan into the binary. We therefore move clang
out, into a separate file in a later commit

fill_default_secondaryCellGroup() is moved to nr_rrc_config.c.
Furthermore, the signature is changes to return the NR_CellGroupConfig
from the functions, instead of filling a pre-allocated structure (which
is, in all cases, allocated just before calling
fill_default_secondaryCellGroup().
There is a problem with this function: the function also fills the
ServingCellConfig (a parameter to this function). This behavior has not
been changed.
nr_DRB_preconfiguration() does a "pre-configuration" for the default DRB
for "noS1" mode, i.e., when there is no connection to core network. In
this case, there is no PDU session to be set up, and hence we need to
preconfigure the DRBs.
We replace this function with partially existing functions and a new
function fill_nr_noS1_bearer_config() which returns a bearer
configuration for the noS1 case, also better reflected in the function
name. It has also been moved to asn1_msg.c, away from the actual PDCP
layer.
For nr_DRB_preconfiguration() and fill_default_secondaryCellGroup(),
there is duplicated code to generate and RLC-BearerConfig, when calling
the existing get_DRB_RLC_BearerConfig() (with the right parameters)
yields a similar configuration (see exceptions below).
Differences:
- We do not support reestablishmentRLC, so we don't set it
- Set prioritisedBitrate to 8kbps instead of infinity (we don't
prioritize anything, anyway)
- bucketSizeDuration is 50ms instead of 100ms
