Cedric Roux fbd69663b1 rlc v2: fix for CU/DU split 
Limitation: this fix only works if there is only one eNB,
because we force module_id = 0 in the function deliver_sdu where
(as the code is today) we have no way to know which module_id is
concerned. More generally, the rlc v2 does not work with more than
1 eNB.

Francesco Mani f73dd0742e Revert "ENDC path switch S1-U: Bugfixes at eNB side. Problem at S1AP E-RAB-Modification-Indication message encoding to be resolved"

Robert Schmidt 8ffe5b4920 Rename UE_list_t to UE_info_t, UE_list_t separate struct 
UE_list_t is now used as a separate list. It can be e.g. used in the
scheduler to mark groups of users. The original UE_list_t is renamed to
UE_info_t to reflect that it is a container for information about UEs.

Cedric Roux f829970085 improve NR UE capabilities request 
Seems like the UEs in the CI don't like when asked to report NR UE
capabilities. So let's first ask for eutra capabilities and then
dig into them to check for en-dc support and only then ask for
NR capabilities. We chose to ask for NR capabilities after receiving
RRCConnectionReconfigurationComplete. That may not be the best thing
to do.

Today, we do nothing with those capabilities. We could completely skip
asking them to the UE, but since the code is there and since it may be
useful in the future, let's do it. Hopefully, it should not hurt too much.

Cedric Roux 51ab31a3b9 trigger NR activation based on RRC measurements 
An NR-capable UE will transmit some NR measurements.
Once received, the whole process on nr-cell addition is started.
It will fail quickly.

Many things are still missing.

What is not handled properly with this commit:
- in x2ap_eNB_handle_sgNB_add_req we hardcode the gNB ID
- nr triggering is done if we receive a measurement but this measurement is
  not analyzed at all
- no timers (T_dc_overall, T_dc_prep) and as is the code fails and then the
  next triggering after UE reconnection will not work (x2 ID are not well
  handled here and there in the code)

Note also that the gNB part has not been looked at all for this commit.

This is work in progress...
