mod_http_oauth2: Enforce client scope restrictions in authorization When registering a client, a scope field can be included as a promise to only ever use those. Here we enforce that promise, if given, ensuring a client can't request or be granted a scope it didn't provide in its registration. While currently there is no restrictions at registration time, this could be changed in the future in various ways.
