Merge remote-tracking branch 'origin/fix-ue-ul-retransmissions-payload-copy' into integration_2024_w21c

A to-be-added UE's RA is added through nr_mac_add_test_ue() (the name is
misleading, it is not a "test UE") through its CellGroupConfig. Using
the process_CellGroupConfig() is unfortunate, because it is not really
clear what part of the CellGroupConfig gets evaluated (it is certainly
not all). Move the code for adding a new RA directly in the user-add
function, and refactor this one.

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.

- addition of control of deltaMCS if enabled in configuration file.
- introduce separate parameter to disable 256QAM in UL
- put min_grant_prb configuration back in pf_ul() as default prb size.

Adds a check for these short payloads and handle correctly

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.
