This commit allows the gNB to handle PDU sessions that the core requests
to setup during the NGAP Initial UE Context Setup. Previously, we only
managed them as part of PDU Session Resource Setup Request.
The RRC will, depending on whether a PDU session is in the NGAP Initial
UE Context Setup, either directly trigger the Security Command, or first
do a bearer setup at the CU-UP. Some asserts have been lifted, as now
the PDU sessions might be present before the RRC Connection is fully
established.
Implement the correct forwarding of the bearers in an F1 UE Context
Setup Request message.
This solves bug #672.
RRC Version is a required IE. Hence, implement the encoder and decoder
for this message. At the DU and CU, read the RRC Version we use and fill
the corresponding field.

- send F1 Setup using callback
- store f1 setup req locally for reference
- check F1 Setup Req against RRC data structures:
* if matches: send F1 Setup Response using callback
* if not matching: send F1 Setup Failure using callback
- don't send CU config update by default, we don't need this
- if the Setup Response does not contain a cell, don't activate. It is
possible the CU sends a gNB-CU configuration update, which will
initialize the structures
The simulators have been changed: due to linker errors that would arise
otherwise, a lot of functions are defined in them to avoid such errors.
Some functions are also defined in header files; in this commit, we
define most functoins in nr_dummy_functions.c, which is compiled in, not
by including the C file, but by adding it to the target in
CMakeLists.txt
- nr_dlsim+nr_ulsim need NR_IF_Module_init(), so it cannot be in
nr_dummy_functions, but the others need it
- Link correcr NR_IF_Module_init() into these simulators, and reduce
overall link list
- Correctly link remaining simulators
