This patch adds a GstMemory as a variable member of the buffer proxy, because we will need to associate the buffer proxy with the memory which exposes it. Later, we will know which memory, in the video buffer pool, is attached to the processed surface. https://bugzilla.gnome.org/show_bug.cgi?id=755072
