mod_muc_rtbl: also filter messages This was a bit tricky because we don't want to run the JIDs through SHA256 on each message. Took a while to come up with this simple plan of just caching the SHA256 of the JIDs on the occupants. This will leave some dirt in the occupants after unloading the module, but that should be ok; once they cycle the room, the hashes will be gone. This is direly needed, otherwise, there is a tight race between the moderation activities and the actors joining the room.

summary: Discard offline stanzas instead of generating stanza errors if mod_offline is not loaded
...

Introduction
============

By default without mod_offline stanzas that would go to offline storage
trigger error stanzas sent back to the sender to inform him of undeliverable stanzas.

But if you use MAM on your server and are certain, all of your clients are using it,
you can use this module to disable the error stanzas.
If mod_offline is loaded, this module will do nothing.

Warning
=======

You most certainly *should not* use this module if you cannot be certain
that *all* your clients support and use MAM!

Compatibility
