Add gst-recorder implementation for weston2.0.0
This commit support virtual display and gst-recorder
function for weston2.0.0.
It is update patch for weston 2.0.0 and based on
562c0c1bb2ef74ccbfda1bae4f84a61828119674
Virtual display is additional display like as offscreen
buffer and it is created from drm-backend.
The gst-recorder is a transfer system using H.264
streaming and Ethernet.
