mod_muc_rtbl: also filter messages
This was a bit tricky because we don't want to run the JIDs
through SHA256 on each message. Took a while to come up with this
simple plan of just caching the SHA256 of the JIDs on the
occupants.
This will leave some dirt in the occupants after unloading the
module, but that should be ok; once they cycle the room, the
hashes will be gone.
This is direly needed, otherwise, there is a tight race between
the moderation activities and the actors joining the room.

--- labels: - Stage-Alpha ... Introduction ============ This is an experimental authentication module that does an asynchronous HTTP call to verify username and password. This is a (possibly temporary) fork of mod_http_auth_async that adds support for authentication using a cookie and SASL EXTERNAL. Details ======= When a user attempts to authenticate to Prosody, this module takes the username and password and does a HTTP GET request with [Basic authentication][rfc7617] to the configured `http_auth_url`. Configuration ============= ``` lua VirtualHost "example.com" authentication = "http_auth_cookie" http_auth_url = "http://example.com/auth" http_cookie_auth_url = "https://example.com/testcookie.php?user=$user" ``` Cookie Authentication ===================== It is possible to link authentication to an existing web application. This has the benefit that the user logging into the web application in their browser will automatically log them into their XMPP account. There are some prerequisites for this to work: - The BOSH or Websocket requests must include the application's cookie in the headers sent to Prosody. This typically means the web chat code needs to be served from the same domain as the web application. - The web application must have a URL that returns 200 OK when called with a valid cookie, and returns a different status code if the cookie is invalid or not currently logged in. - The XMPP username for the user must be passed to Prosody by the client, or returned in the 200 response from the web application. Set `http_cookie_auth_url` to the web application URL that is used to check the cookie. You may use the variables `$host` for the XMPP host and `$user` for the XMPP username. If the `$user` variable is included in the URL, the client must provide the username via the "authzid" in the SASL EXTERNAL authentication mechanism. If the `$user` variable is *not* included in the URL, Prosody expects the web application's response to be the username instead, as UTF-8 text/plain. Compatibility ============= Requires Prosody trunk
