Start re-working SwapBuffers.

intelCopyBuffer() is now intelDisplayBuffer(): it displays the given surface
in the on-screen window.
Added a pipe_surface parameter to winsys->flush_frontbuffer().
Front buffer rendering/flushing actually works now.
But, we should only allocate the front surface on demand...
