Although it is pretty unusual the stride for the guest image and the
mirror image maintained by spice-display can be different. So use
separate variables for them.

Add fast path to qemu_spice_display_switch in case old and new
displaysurface have identical size (happens with display panning
and page flipping). We just swap the backing store then and don't
go through the whole process of deleting and creating the primary
surface.
To simplify the code a bit move mirror surface allocation to
qemu_spice_display_switch().

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.

Related spice-only bug. We have a fixed 16 MB buffer here, being
presented to the spice-server as qxl video memory in case spice is
used with a non-qxl card. It's also used with qxl in vga mode.
When using display resolutions requiring more than 16 MB of memory we
are going to overflow that buffer. In theory the guest can write,
indirectly via spice-server. The spice-server clears the memory after
setting a new video mode though, triggering a segfault in the overflow
case, so qemu crashes before the guest has a chance to do something
evil.
Fix that by switching to dynamic allocation for the buffer.

This patch fixes spice display initialization to handle
multihead properly.
spice-core now keeps track of which QemuConsole has a spice
display channel attached to it and which has not. It also
manages display channel ids.
spice-display looks at all QemuConsoles and will pick up any
graphic console not yet bound to a spice channel (which in practice
are all non-qxl graphic devices).
Result is that
(a) you'll get a spice client window for each graphical device
now (first only without this patch), and
(b) mixing qxl and non-qxl vga cards works properly.

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.

Add QemuConsole parameter to vga_hw_*, so the interface allows to update
non-active consoles (the actual code can't handle this yet, see next
patch). Passing NULL is allowed and updates the active console, like
the functions do today.
While touching all vga_hw_* calls anyway rename that to the functions to
hardware-neutral graphics_hw_*

Stop abusing displaysurface fields for text mode displays.
(bpp = 0, width = cols, height = lines).
Add flags to displaystate indicating whenever text mode display
(curses) or gfx mode displays (sdl, vnc, ...) are present.
Add separate displaychangelistener callbacks for text / gfx mode
resize & updates.
This allows to enable gfx and txt diplays at the same time and also

With the next qemu version (1.3) we are going to bump the qxl device
revision to 4. The new features available require a recent spice-server
version, so raise up the bar. Otherwise we would end up with different

would be a major PITA when it comes to compat properties.

The current intptr_t casts are a problem when the address's highest
bit is 1, and it is cast to a intptr_t and then to uint64_t, such
as at:
surface.mem = (intptr_t)ssd->buf;
This causes the sign bit to be extended which causes a wrong address to
be passed on to spice, which then complains when it gets the wrong
slot_id number, since the slot_id is taken from the higher bits.
The assertion happens early - during the first primary surface creation.
This fixes running "-vga qxl -spice" with 32 bit compiled
qemu-system-i386.

Today, when notifying a VM state change with vm_state_notify(),
we pass a VMSTOP macro as the 'reason' argument. This is not ideal
because the VMSTOP macros tell why qemu stopped and not exactly
what the current VM state is.
One example to demonstrate this problem is that vm_start() calls
vm_state_notify() with reason=0, which turns out to be VMSTOP_USER.
This commit fixes that by replacing the VMSTOP macros with a proper
state type called RunState.

Add support for the spice tablet interface. The tablet interface will
be registered (and then used by the spice client) as soon as a absolute
pointing device is available and used by the guest, i.e. you'll have to
configure your guest with '-usbdevice tablet'.
With that patch applied you'll actually see the guests screen in the
spice client. This does *not* bring qxl and full spice support though.
This is basically the qxl vga mode made more generic, so it plays
together with any qemu-emulated gfx card. You can display stdvga or
cirrus via spice client. You can have both vnc and spice enabled and
clients connected at the same time.
