From 3d186f7b97c508cc16955a96a69ee5d6c9db57dc Mon Sep 17 00:00:00 2001
From: George Kiagiadakis <george.kiagiadakis@collabora.com>
Date: Thu, 23 May 2019 18:59:05 +0300
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.
