Security part needs to be checked, may fail to work.
But if it fails, it was probably not working before either.
This commit also contains adding 'static' to nr_pdcp_entity_release()
and nr_pdcp_entity_delete() (it was too complicated to do a separate
commit for this).
We also update stats in free_rx_list() (again, too complicated for
a separate commit).
openair2/RRC/NR/rrc_gNB.c probably needs some more work, it is a
bit ugly to reestablish all the drbs without checking if they
exit. It will generate warnings at runtime. I didn't do it because
I don't know the proper way.
Closes#685 and #698

- PRACH Configuration Index = 98 is not suSpported by the Amarisoft UE simulator, as a number of PRACH occasions within the PRACH slot is > 1
- for PRACH Configuration Index = 100, number of time-domain PRACH occasions within a PRACH slot is 1
Multiple DUs host cells, whose cell ID cannot match (to identify them
uniquely). Hence, don't check for equality with CU, because otherwise,
we can never connect multiple DUs.
This is a workaround for a problem described in #706. In short, we
cannot reuse the cu_add/remove_f1_ue_data() functions if we are in an
integrated CU-UP/CP ("CU"), but then we can also not reliably use
different UE IDs in CU-UP and CU-CP (except if using even more hacks).
An assoc_id of 0 is used to mark UEs whose DU is "offline" (not
connected). In this patch, if a DU disconnects, we go through all UEs
and set their assoc_id to 0 if they belong to a UE that just went
offline.
