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.

Add flags to displaystate indicating whenever text mode display

Add separate displaychangelistener callbacks for text / gfx mode
resize & updates.

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
qxl revisions depending on the spice-server version installed, which
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.
