backport: merge bitcoin#19763, #20653, #20756, #19315, #20646, #21015, #19771, #21425, #21236, #21198, #21707, #21785, #21506, #22107, partial bitcoin#21186, merge gui#226, partial gui#206 (networking backports: part 2)

[kwvg]

Additional Information

• bitcoin#19763 doesn't play nice on its own, p2p_addr_relay.py fails because of assert_equal(total_ipv4_received, num_ipv4_addrs * ipv4_branching_factor) where not(0 == 20). It only works with bitcoin#21707.
• In the GUI/Qt wallet, the peer information tab in the debug window has three fields added to them, "Wants Tx Relay", "Last Block" and "Last Tx".
• The RPC help text for getpeerinfo now includes help text for the permissions return value and a debug RPC called addconnection has been introduced.

Breaking Changes

None observed.

LGTM, see a couple of nits below + it would be nice if commit messages for gui backports would say merge bitcoin-core/gui#<number> .... (and not just merge gui#<number>). This would turn them into clickable links making PR review a bit easier ;)

it would be nice if commit messages for gui backports would say merge bitcoin-core/gui# .... (and not just merge gui#).

Yes; please do not use non-standard messages. My script assumes for gui

    "bitcoin-core/gui" 

and for non-gui

            if ("bitcoin #" + number) in item or ("bitcoin#" + number) in item or ("merge #" + number) in item or \
