mod_http_oauth2: Add role selector to consent page
List includes all roles available to the user, if more than one.
Defaults to either the first role in the scope string or the users
primary role.
Earlier draft listed all roles, but having options that can't be
selected is bad UX and the entire list of all roles on the server could
be long, and perhaps even sensitive.
Allows e.g. picking a role with fewer permissions than what might
otherwise have been selected.
UX wise, doing this with more checkboxes or possibly radio buttons would
have been confusion and/or looked messier.
Fixes the previous situation where unselecting a role would default to
the primary role, which could be more permissions than requested.

# 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" } ```
