spice/gl: render DisplaySurface via opengl
This switches over spice (in opengl mode) to render DisplaySurface
updates into a opengl texture, using the helper functions in
ui/console-gl.c. With this patch applied spice (with gl=on) will
stop using qxl rendering ops, it will use dma-buf passing all the
time, i.e. for bios/bootloader (before virtio-gpu driver is loaded)
too.
This should improve performance even using spice (with gl=on) with
non-accelerated stdvga because we stop squeezing all display updates
through a unix/tcp socket and basically using a shared memory transport
instead.
