fixes the overflow issue in the PUCCH2 RX with 4+ RX antennas and 12+
bits (polar code format). The fix scales the polar decoding LLR
computation according to the number of RX antennas. The issue was clear
for 100 MHz 4 RX antennas. Even

  nr_pucchsim -s -5 -q 8 -P 2 -b 12 -R 273 -z4 -n1000

doesn't converge to 0 BLER with increasing SNR. The issue didn't appear
in CI because of the bandwidth and antenna count limitations.

On Wayland (e.g., Gnome on Ubuntu 22), additional steps might be
necessary to make QtScope run. Describe them in the doc.

Closes: #696

- this prevents pulling PDUs from PDCP when re-establishment is awaiting

- short and long SN sizes
- PDCP PDU header sizes
- PDCP integrity size
- getter for maximim PDCP PDU size

From 3GPP TS 38.321 Section 5.4.3 Multiplexing and assembly, we need to process the highest priority subPDUs first:
- MAC CE for C-RNTI is the one with higher priority

38.473 section 8.2.3.1 says that upon F1 Setup Request, UE associated
signalling should be erased. In this commit, we trigger a release of all
UEs that were still connected to a DU when we received the SCTP
shutdown, i.e., when the DU disconnects.

Closes #762

Explanations: see #706. TLDR: the RRC code calls nr_pdcp_remove_ue(), so
we should not call it in the E1 handler if we do not use split mode.

5G L2sim is broken since some time, and there is no time to fix it.
Remove it from the Container Parent Pipeline.

- Four mounting of files, we need the absolute path. Even if the script
  gets relative paths, realpath will give the absolute path
- Correctly recognize and handle gNB images with AW2S support

- no need to specify "single-ue" profile when running iperf test for 1 UE only
- default profile "balanced" can be used instead, computes BW for 1 UE correctly
