It can happen that in the current DL slot, we cannot send an allocation for Msg3 in a later UL slot. Up to this commit, MAC printed a warning. However, this is not really a warning, as it will likely work in the next or a later slot. So demote this to debug.

The starting point was the function do_NR_DLInformationTransfer() which may deal with more than 256 bytes. Then why not cleanup all the functions in the same file. (And do a bit of formattting fixing while we're here.) Then cleanup the callers of those functions. Then, because of do_SIB23_NR() let's also cleanup in some structures. Not all the codebase was cleaned up, there surely remain some uint8_t (and char/short/uint16_t) which are wrong.

In some pipelines, it happens that iperf3 is hanging on 100% CPU load. In these cases, a simple TERM signal does not seem to be enough to kill it; KILL is necessary. While e.g., RemoteCmd's driver paramiko has a timeout command, the documentation [1] is not really clear how it is trying to stop commands. Since it effectively does not stop, we have to assume it is only sending TERM. To remedy this, use the timeout command to start iperf3. We use option -v for diagnose timeouts on stderr, and send KILL after an additional 3 seconds (-k3) if TERM does not succeed. The timeout is sent to the same duration as the overall iperf timeout.

make sure the SSB is offset by 4 PRBs from the BW start. Therefore, the ARFCN for the SSB center must be offset by 14 PRB from the ARFCN for the BW start.

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.
