mod_http_oauth2: Limit revocation to clients own tokens in strict mode
RFC 7009 section 2.1 states:
> The authorization server first validates the client credentials (in
> case of a confidential client) and then verifies whether the token was
> issued to the client making the revocation request. If this
> validation fails, the request is refused and the client is informed of
> the error by the authorization server as described below.
The first part was already covered (in strict mode). This adds the later
part using the hash of client_id recorded in 0860497152af
It still seems weird to me that revoking a leaked token should not be
allowed whoever might have discovered it, as that seems the responsible
thing to do.

# 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" } ```
