removing aerial_vnf_nr_aerial_p7_start_thread

removing assert on RACH num_preambles>1. Instead we print an error and continue RA with only the first preamble.

In NSA, the RA process contains the RNTI of the UE to add. The previous
implementation would not remove the RNTI in NSA/for CFRA, which is
unclear (why should it stay? RA is over). Also, we did not clear all
contents, which masked a bug, as we were reusing an RA process for a
subsequent attach, leading to a segfault on reattach. That is fixed in
this commit.

Also, we were using the RA structure after having cleared it in
_nr_rx_sdu(), which semantically makes no sense.

To harmonize handling of the preambles: completely reset the RA
processes inside nr_clear_ra_proc(). For SA, also add the initialization
of allowed preambles.

Finally, this commit fixes a memory leak: we always (also in SA) fill a
list of preambles in a dynamically allocated preamble list. Since the
total list is only up to 64 preambles of 1B each, put it directly into
the struct instead of dynamically allocating it.

Remove the secondaryCellGroup variable in RRC, as it is not used there.

Note that in the case of F1, the secondaryCellGroup entirely belongs to
the DU, i.e., MAC. Also, we don't do anything with it in RRC.

NSA is quite verbose, some messages are large and it is not very
"interesting" for the average user. The logs can be enabled on demand,
or directly seen in Wireshark instead.

The RRC UE context has the RRC UE ID. Use that instead of hardcoding
something that might be wrong (because the RRC UE ID can be reused,
whereas the counter just blindly increases).

The next commit will use that RRC UE ID to free the PDCP context for the
UE. It might be wrong on reattach otherwise, because the RRC UE ID could
again be 1.

We simply don't need to modify the servingCellConfig, so don't do it.

Variable spCellConfig is only used in function rrc_add_nsa_user(). Make
it local to this function to prevent possible bugs (limit the possible
scope as much as possible).

Variable reconfig is only used in function rrc_add_nsa_user(). Make it
local to this function to prevent possible bugs (limit the possible
scope as much as possible).

Simplify code by returning an allocated object to a CG_Config.  It leads
to less code and is easier to reason about, because each call will
return a new CG_Config, which can be freed, irrespective of other calls
to fill_default_reconfig().

of other calls to fill_default_reconfig().

get_default_secondaryCellGroup() would "sanitize" the servingCellConfig,
i.e., remove BWP that are invalid. However, it is difficult to
understand (we can do sanitization once at the beginning) and reason
(why the servingCellConfig is modified in
get_default_secondaryCellGroup(), because all we want is a new
CellGroupConfig, without modifying other data structures).

Instead, do sanitization once after reading the configuration in
gnb_config.c. Also, modify physical simulators nr_dlsim and nr_ulsim to
apply this sanitization before a call to
get_default_secondaryCellGroup(), as the latter would have done the
sanitization.

This reverts commit 4c658cdd.

This commit was introduce to signal a known segfault. The bug has been
fixed in the last commit, so this commit can be reverted as the
AssertFatal is not necessary anymore.

Prior to this commit, upon a release of a UE at the gNB in NSA, the gNB
fails with a segv. This is because the servingCellConfigCommon is used
in the reconfigurationWithSync (through a simple pointer). At the
release, the entire secondaryCellGroup is freed, leading to a free of
the servingCellConfigCommon. The gNB then tries to use it (e.g., for
looking up the numerology), and leading to a segv.

To avoid this problem, make a "deep copy" of the ServingCellConfigCommon
so that we can safely free the UEs secondaryCellGroup, without freeing
the initial ServingCellConfigCommon.
