Jonas Ådahl ff7a42b8bc wayland: Add API to acquire a CoglScanout from a surface
This will check whether the current backing buffer is compatible with
the primary plane of the passed CoglOnscreen. Since this will extend the
time before a buffer is released, the MetaWaylandBufferRef is swapped
and orphaned if a new buffer is committed before the previous one was
released. It'll eventually be released, usually by the next page flip
callback.

Currently implemented for EGLImage and DMA-BUF buffer types.
