4423184376 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.

9f5c6d06ad spice/gl: Enable dmabuf only for spice >= 0.13.1
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).

474114b730 spice: add opengl/virgl/dmabuf support
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.

dc8dceee64 spice: set pointer position on hotspot

0b2824e5e4 spice: use bottom half instead of refresh timer for cursor updates
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.

284d1c6b3b console: allow pinning displaychangelisteners to consoles
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.

0b0878611c qemu-pixman.h: Avoid mutual inclusion loop with console.h
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.
