This protocol enables explicit synchronization of asynchronous graphics
operations on buffers on a per-commit basis. Support is currently
limited to dmabuf buffers and dma_fence fence FDs.
Explicit synchronization provides a more versatile notification
mechanism for buffer readiness and availability, and can be used to
improve efficiency by integrating with related functionality in display
and graphics APIs.
Finally, the per-commit nature of the release events provided by this
protocol offer a solution to a deficiency of the wl_buffer.release event

Yes, I have been working locally with this revision in Weston, and
everything builds and runs fine.
