mod_http_oauth2: Implement RFC 8628 Device Authorization Grant Meant for devices without easy access to a web browser, such as refrigerators and toasters, which definitely need to be running OAuth-enabled XMPP clients! Could be used for CLI tools that might have trouble running a http server needed for the authorization code flow.

This module discards typing notifications sent to a bare host JID,
preventing error replies to be sent. These errors are harmless but can
be annoying sometimes if your client shows them prominently.
