[Libva] [PATCH gstreamer-vaapi] wayland: Port to 1.0 version of the protocol

[Rob Bradford]

From: Rob Bradford <rob at linux.intel.com>

This patch updates to relect the 1.0 version of the protocol. The main changes
are the switch to wl_registry for global object notifications and the way
that the event queue and file descriptor is processed.
