mod_http_oauth2: Validate consistency of response and grant types
Ensure that these correlated fields make sense per RFC 7591 ยง 2.1, even
though we currently only check the response type during authorization.
This could probably all be deleted if (when!) we remove the implicit
grant, since then these things don't make any sense anymore.

# mod_ogp This module adds [Open Graph Protocol](https://ogp.me) metadata to URLs sent inside a MUC. With mod_ogp enabled, when a user sends a URL in a MUC (where the message has its `id` equal to its `origin-id`), the module calls the URL and parses the result for `<meta>` html tags that have any `og:...` properties. If it finds any, it sends a [XEP-0422 fastening](https://xmpp.org/extensions/xep-0422.html) applied to the original message that looks like: ```xml <message id="example" from="chatroom@muc.example.org" to="user@chat.example.org/resource"> <apply-to xmlns="urn:xmpp:fasten:0" id="origin-id-X"> <meta xmlns="http://www.w3.org/1999/xhtml" property="og:title" content="The Rock"/> <meta xmlns="http://www.w3.org/1999/xhtml" property="og:url" content="https://www.imdb.com/title/tt0117500/"/> <meta xmlns="http://www.w3.org/1999/xhtml" property="og:image" content="https://ia.media-imdb.com/images/rock.jpg"/> </apply-to> </message> ``` The module is intentionally simple in the sense that it is basically a transport for https://ogp.me/ Configuration ------------- You can present an allowlist or denylist of domains for which OGP metadata will be fetched via the `ogp_domain_allowlist` and `ogp_domain_denylist` settings repectively. For example: ```lua Component "muc.example.org" "muc" modules_enabled = { "ogp" } ogp_domain_allowlist = { "prosody.im" } ```
