mod_http_oauth2: Improve error messages for URI properties Since there are separate validation checks for URI properties, including that they should use https, with better and more specific error reporting. Reverts 'luaPattern' to 'pattern' which is not currently supported by util.jsonschema, but allows anything that retrieves the schema over http to validate against it, should they wish to do so.

# mod_muc_batched_probe

This module allows you to probe the presences of multiple MUC occupants or members.

XEP-0045 makes provision for MUC presence probes, which allows an entity to
probe for the presence information of a MUC occupant (or offline member).

See here: https://xmpp.org/extensions/xep-0045.html#bizrules-presence

This module creates the possibility to probe with a single IQ stanza the
presence information of multiple JIDs, instead of having to send out a presence
probe stanza per JID.

The IQ stanza needs to look as follows:

```
   <iq from="hag66@shakespeare.lit/pda"
      id="zb8q41f4"
      to="chat.shakespeare.lit"
      type="get">

      <query xmlns="http://jabber.org/protocol/muc#user">
         <item jid="hecate@shakespeare.lit"/>
         <item jid="crone1@shakespeare.lit"/>
         <item jid="wiccarocks@shakespeare.lit"/>
         <item jid="hag66@shakespeare.lit"/>
      </query>
   </iq>
```



## Configuration

Under your MUC component, add `muc_batched_probe` to `modules_enabled`

```
   Component "conference.example.org" "muc"
      modules_enabled = {
               "muc_batched_probe";
      }
```
