MUC: Don't default component admins to being room owners This change has various technical and social benefits. If ownership of a MUC is really needed, it can be gained using the 'Set affiliation' ad-hoc command or prosodyctl shell. Example client incompatibility with the old behaviour: - https://github.com/monal-im/Monal/issues/1085

MUC: Add per-room PM restriction functionality (thanks Wirlaburla) Based on mod_muc_restrict_pm in prosody-modules d82c0383106a

scansion: Add roster groups setting to pubsub form in tests

scansion: Enable blocklist compat during tests to fix CI

util.prosodyctl: Use notify socket to wait for Prosody to be ready Previously, prosodyctl only waits for the pidfile to appear, which does not necessarily mean that Prosody is fully ready to receive traffic. By waiting until Prosody says it's ready via the systemd notify socket we know for sure that Prosody is really ready. Notably this should ensure that when running `make integration-test` Prosody is really ready when Scansion starts running tests. Not sure if this timeout handling is optimal.

net.server_epoll: Add support for systemd socket activation Allows creating listening sockets and accepting client connections before Prosody starts. This is unlike normal Prosody dynamic resource management, where ports may added and removed at any time, and the ports defined by the config. Weird things happen if these are closed (e.g. due to reload) so here we prevent closing and ensure sockets are reused when opened again.

mod_admin_shell: Allow matching on host or bare JID in c2s:show Only supporting exact match on full JID isn't helpful if you want to list sessions per host or user. Backport of 430333198e4c Fixes #1857

mod_blocklist: Drop blocked messages without error, option to restore compliant behavior From XEP-0191: > For message stanzas, the server SHOULD return an error, which SHOULD > be <service-unavailable/>. Following this may leak to a blocked JID that they have been blocked, which seems contrary to the goal of pretending to be perpetually offline.

mod_pep: Implement 'roster' (group) access_model Allows e.g. restricting your vcard4 to only family or similar. Notes: This does not include roster groups in the configuration form, so the client will have to get them from the actual roster.

mod_announce: Suppress luacheck warnings

mod_announce: Add shell commands and APIs for sending to all/online/roles

prosodyctl shell: Fix invocation with 3+ command arguments The code correctly inserted the ',' when there was already a "%q" in the format string, but then the next argument would fail to match because it inserted ", %q" instead of "%q". The code now matches both, ensuring the generated code will not produce a syntax error with multiple arguments.

mod_blocklist: Fix fix signal for letting stanzas pass Returning nothing/nil lets stanzas pass, returning anything else blocks
