mod_vcard_muc: Add an alternative method of signaling avatar change When the avatar has been changed, a signal is sent that the room configuration has changed. Clients then do a disco#info query to find the SHA-1 of the new avatar. They can then fetch it as before, or not if they have it cached already. This is meant to be less disruptive than signaling via presence, which caused problems for some clients. If clients transition to the new method, the old one can eventually be removed. The namespace is made up while waiting for standardization. Otherwise it is very close to what's described in https://xmpp.org/extensions/inbox/muc-avatars.html

summary: Monkeypatch mod_smacks to silently discard unacked message stanzas when a hibernation times out
...

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

By default mod_smacks sends back error stanzas for every unacked message
stanza when the hibernation times out.
This leads to "message not delivered" errors displayed in clients.

When you are certain that *all* your clients use MAM, this is unnecessary and
confuses users (the message will eventually be delivered via MAM).

This module therefore monkeypatches mod_smacks to silently drop those
unacked message stanzas instead of sending error replies.
Unacked iq stanzas are still answered with an error reply though.

If you disable mod_offline, this module will also silence "message not delivered"
error messages that will otherwise be generated when prosody would normally
store offline message but can't do this because of disabled mod_offline.  
If mod_offline is *not* disabled this module will not change offline storage
behaviour at all.

Warning
=======

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