From 3d186f7b97c508cc16955a96a69ee5d6c9db57dc Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/2] extensions: implement Endpoint & ClientEndpoint
 interfaces

The ClientEndpoint interface allows session managers to register
endpoint objects on pipewire.
The Endpoint interface allows other clients to interact with
endpoints provided by the session manager.
