Introduce new LC configuration "priority", as specified in 38.321, and
use to sort LCs by priority. We set the priority of an SRB according to
38.331 Section 9.2.1, and for a DRB to be the minimum priority of the
QoS flows associated to this DRB.

Introduce new functions to add/release LCs without needing to go through
the intermediate CellGroupConfig. This harmonizes LC handling at the "DU
handler" to keep it consistent with RLC bearer handling.

These functions allow to group LC configuration handling, and we can
remove functions for setting NSSAIs and QoS by handling in one central
place (while adding LCs).

nr_mac_add_test_ue() is used by simulators and also in NSA mode to add a
new UE. Ideally, these users should also call the ue context setup
request handler to add a UE context; for the moment, respect the passed
list of LCs to add. Similarly, for do-ra, we require a dedicated
function to still parse the CellGroupConfig, so we keep that part of
functionality.

On reestablishment, since we do not process the CellGroupConfig from the
old UE, we need to add LCs for the new UE based on the onces from old
UE.

Use a common structure nr_lc_config_t to group LC configuration for one
logical channel. Use seq_arr for simple lookup, adding, removing of
elements without manual indexing logic.

This commit retains the previous logic of adding/releasing LCs through
the process_CellGroupConfig(), although we know while building the
CellGroupConfig if we add/release LCs. The next commit fixes this.

In later commits, we will call these functions from multiple places in
the scheduler, so move them to a central place.

If we do not make this change, with the next commit, we get the
following error from gcc:

  openair2/E2AP/RAN_FUNCTION/O-RAN/ran_func_kpm.c:299:46: error: assignment of read-only location '*(arr_ue_id.ue_info_list + (sizetype)(arr_ue_id.sz * 2444864))'
  |         arr_ue_id.ue_info_list[arr_ue_id.sz] = *ue;

In a later commit, we will use find_if in L2. In the case of building
with E2 agent, we link e2_agent which comes with its own implementation
of find_if_arr(), which results in a name clash. Rename the OAI
implementation, as nothing uses this, anyway.

This reverts commit 0d0e1111.  It was
set to UE RX to TX time to 2 as it was deemed that the UE could sustain
this time. However, we noticed a degradation of performance, so reset
the RX to TX time to something higher to ensure proper performance.

This reverts commit 31b4f48e.

rename persisted ul harq status per pid with a uniq name as this variable is persisted in memory and accessed by multiple threads, a uniq name helps to debug

uper_encode_to_buffer() of asn1c returns the number of BITS that have
been encoded; if we use this, we need to calculate the resulting number
of bytes (rounding up) to get the right buffer size.

Note that do_NR_ULInformationTransfer() uses
uper_encode_to_new_buffer() which returns the number of BYTES, hence, in
this similar function, we should not modify the return value.

-Corrected the conversion function used in CU_handle_F1_SETUP_REQUEST

-Corrected the conversion function in CU_handle_gNB_DU_CONFIGURATION_UPDATE

add a function to reset the transmission timestamps chain, and use it in context of UE resynchronization

Removed arbitrary offset of 30dB.
Changed sign for pathloss: pathloss calculated in compute_nr_SSB_PL is the difference between transmitted and received power.
Transmission power for preamble should compensate the pathloss, therefore power should increase with pathloss.
