mod_mam: Allow plugging into archive decision Similar procedure as mod_csi_simple

core.certmanager: Ensure key exists for fullchain Since 5cd075ed4fd3 any file matching "fullchain" would be considered for use. Dehydrated stores fullchain certs in e.g, fullchain-1641171024.pem and a symlink fullchain.pem pointing at the latest one. However the current rule for finding a corresponding private key would try privkey-1641171024.pem in the same directory, which may not exist.

mod_admin_shell: Use a table to show help sections Because tables make everything better and more readable!

CHANGES: Mention graceful shutdown

mod_c2s: Ignore unused event payload [luacheck]

mod_c2s,mod_s2s: Wait for sessions to close before proceeding with shutdown steps Ensures unavailable presence and other outgoing stanzas are sent. Waiting for c2s sessions to close first before proceeding to disable and close s2s ensures that unavailable presence can go out, even if it requires dialback to complete first.

mod_c2s: Close ports in a separate, earlier event from closing sessions Lets other things step in and do things while c2s ports are closed, e.g. mod_smacks, or other modules with port handlers that forward to c2s.

mod_s2s: Disable creation of new outgoing connections during shutdown

mod_c2s,mod_s2s: Disable and close port listeners before closing sessions This ensures no new clients can start connecting during shutdown

mod_posix: Run signal handlers in the startup thread
