mod_http_oauth2: Strip unknown extra fields from client registration We shouldn't sign things we don't understand! RFC 7591 section-2 states: > The authorization server MUST ignore any client metadata sent by the > client that it does not understand (for instance, by silently removing > unknown metadata from the client's registration record during > processing). Prevents grandfathering in of unvalidated data that might become used later, especially since the 'additionalProperties' schema keyword was removed in 698fef74ce53

# Introduction

This module adds a room configuration option to hide inline media from
unaffiliated users in MUCs and display them as links instead.

This can be useful in public channels where content posted by users should not
be shown by default.

# Configuring

## Enabling

``` {.lua}
Component "rooms.example.net" "muc"
modules_enabled = {
    "muc_restrict_media";
}
```

## Settings

A default setting can be provided in the config file:

``` {.lua}
muc_room_default_restrict_media = true
```
