Feature: Websocket: Allow to access TLS channel binding data
As a client developer i want to provide additional security against man in the middle attacks. There exists various SCRAM-PLUS methods for authentication where the client must provide TLS channel binding data in the auth process. (https://www.rfc-editor.org/rfc/rfc7677.html)
GLib introduced Gio.TlsConnection.get_channel_binding_data()
in recent versions, which we use when we don't use websocket.
For websocket connections we use libsoup, but there is no way currently to get the channel binding data.
