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.

After 474114b7 the dmabuf feature is enabled whenever spice
greater than or equal to spice 0.13.0 is found. This is because
two new functions are required: spice_qxl_gl_scanout and
spice_qxl_gl_draw_async. These were, however, introduce in 0.13.1
release. Well, technically they haven't been released yet, but
for sure they are not going to be part of 0.13.0 release (for the
ABI stability sake).

This adds support for dma-buf passing to spice. This makes virtio-gpu
with 3d acceleration work with spice.
Workflow:
* virglrenderer renders the guest command stream into a texture.
* qemu exports the texture as dma-buf and passes on that dma-buf
to spice-server.
* spice-server passes the dma-buf to spice-client, using unix
socket file descriptor passing.
* spice-client asks the window systems composer to render the
dma-buf to the screen.
Requires cutting edge spice (server) and spice-gtk (client) builds,
from git master branch.
Also requires libvirt managing your qemu instance, and using
"virt-viewer --attach $guest". libvirt will connect spice-server and
spice-client using unix sockets instead of tcp sockets then, which
is required for file descriptor passing.
Works for the local case (spice server and client on the same machine)
only. Supporting remote too is planned (by feeding the dma-bufs into
gpu-assisted video encoder), but not there yet.
gl mode is turned off by default, use "-spice gl=on,$otherargs" to
enable it.

The Spice protocol uses cursor position on hotspot: the client is
applying hotspot offset when drawing the cursor.

Calling directly doesn't work due to the qxl-render code running in
spice server thread context. Meanwhile bottom half scheduling is
thread-safe though, so we can use that to kick a cursor update in
main i/o thread context.

So you'll have a mouse pointer when running non-qxl gfx cards with
mouse pointer support (virtio-gpu, IIRC vmware too).

DisplayChangeListener gets a new QemuConsole field, which can be set to
non-NULL before registering. This will pin the QemuConsole, so that
particular DisplayChangeListener will not follow console switches.
spice+gtk (which don't support text console input anyway) are switched
over to be pinned to console 0, which usually is the graphical display.

Use QemuConsole instead. Updates interfaces in console.[ch] and adapts

Remove an unnecessary mutual inclusion loop between qemu-pixman.h and
console.h, since the former was only including the latter for
'PixelFormat*', which can be provided by typedefs.h. This requires a
minor adjustment to the files which included qemu-pixman.h, since
they were relying on it implicitly dragging in all of console.h.
