mod_firewall: Load marks from storage on demand rather than at login This ensures people who don't use marks, or use them infrequently, don't pay a perf cost on every resource bind.

mod_firewall: Log warning when attempting to mark/unmark remote users

mod_firewall: enable marks by default

mod_firewall: Improve error when mark name contains invalid characters

mod_firewall: marks: Fix marking a user with no previous marks

mod_firewall: Update user marks to store instantly via map store The original approach was to keep marks in memory only, and persist them at shutdown. That saves I/O, at the cost of potentially losing marks on an unclean shutdown. This change persists marks instantly, which may have some performance overhead but should be more "correct". It also splits the marking/unmarking into an event which may be watched or even fired by other modules.

mod_firewall: Split some long lines [luacheck]

mod_firewall: Fix inverted logic of 'FROM FULL JID?'

mod_firewall: spam-blocking.pfw: Remove requirement for invites to have no body Some clients (e.g. Gajim) send a body, which I guess makes sense. The bare JID sender check should already make it hard to bypass this (i.e. a normal client putting muc#user into a normal chat message shouldn't bypass the usual message filters).

mod_firewall: scripts: spam-blocklists: Check sender and inviter of MUC invitations against blocklist
