pixman/vnc: use pixman images in vnc.
The vnc code uses *three* DisplaySurfaces: First is the surface of the actual QemuConsole, usually the guest screen, but could also be a text console (monitor/serial reachable via Ctrl-Alt-<nr> keys). This is left as-is. Second is the current server's view of the screen content. The vnc code uses this to figure which parts of the guest screen did _really_ change to reduce the amount of updates sent to the vnc clients. It is also used as data source when sending out the updates to the clients. This surface gets replaced by a pixman image. The format changes too, instead of using the guest screen format we'll use fixed 32bit rgb framebuffer and convert the pixels on the fly when comparing and updating the server framebuffer. Third surface carries the format expected by the vnc client. That isn't used to store image data. This surface is switched to PixelFormat and a boolean for bigendian byte order.
