hotfix: current vlm_master (5fa129cf3161da9ff2d67341e6277e818c0f5d6a)
breaks F1, NG, so use the one before

* nb_re_pdsch is directly linked to nb_rb_pdsch, if the latter is 0 the
  former is also 0
* compute average channel level only when number of RE for PDSCH is not 0
  the average channel level will be set to 0 otherwise
* Added a log message to handle this special case, which is consequence
  of other issues in the RX chain
* with this commit, the inconsistency in the RX chain will be handled
  in later in nr_ue_pdsch_procedures with a demodulation failure

other minor changes:

* Improved clarity by using NR_NB_SC_PER_RB instead of hard-coded value 12 in nb of RBs calculation
* cleaned up unused variable and outdated comments

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.

UE was attempting to send ACK on MSG2 - was caused by missing brackets in if statement.

Set appropriate length for csi payload calloc and memcpy, according to bit_len

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.
