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

Introduction
------------

This module attempts to restrict use of non-whitelisted XEP-0065
proxies.

Configuration
-------------

Without any options, the module will restrict users to local [proxy65
components](https://prosody.im/doc/modules/mod_proxy65).

    -- additional proxies to allow
    allowed_streamhosts = { "proxy.eu.jabber.org" }

The module will add all local proxies to that list. To prevent it from
doing that, set

    allow_local_streamhosts = false
