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.

- 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
