This commit introduces several enhancements in X2AP and RRC to deal
with ENDC. The main goal is to deal with UE's on/off and with various
errors.
The following work is included:
- DC prep and DC overall X2 timers
- X2 messages for UE release and DC timers' timeout
Open problems:
- what to do when the UE sends an scg Failure? This commit removes
the UE. And this removal may not be correctly done
- UE removal in the gNB's PHY layer (a next commit is coming,
but it is hackish and will need a rework)
also correction for Circular Dependency Protection on header files
also correction on the banner check

RLC has timers. We need to keep track of time. We chose to not use
realtime but 'processing time'. That is we send a tick to RLC for every
subframe when it is processed by the softmodem. Before this commit we
used to increase time in the function mac_rlc_status_ind which is called
for every subframe in the eNB, but not in the gNB (at least not in the
current gNB). So we need another way to keep track of time.
The function gNB_dlsch_ulsch_scheduler is called for every slot. It seems
to be the perfect candidate to send a tick to RLC for every subframe. We
take care of subcarrier spacing to send every subframe (one subframe is
always 1ms), not every slot (slot duration depends on subcarrier spacing).
It may not be the best solution. To be revised if needed.
Note: the UE has not been fixed. Some modification is needed for the UE
too, most probably.
Create a temporary rrc_eNB_ue_context_t when it can't be obtained from
current RRC state:
- if UE was not attached to current eNB
- when RRCConnectionReestablishmentRequest has a wrong encoding
- in all other cases when ue_context_p can't be obtained.

The following Merge Requests have been included:
* MR [878] : CI framework update for 5G NSA FR1 setup
* MR [885] : PTRS-based UL phase compensation
I had to remove the Msg2 transmission in phytest mode, which was present in branch 'benetel_integration'.
This caused following assertion:
Assertion (Foffset <= Ncb) failed!
In nr_rate_matching_ldpc() /home/sli/sudas-demonstrator/openair1/PHY/CODING/nr_rate_matching.c:411
Foffset 6492 > Ncb 924
