qxl creates a pipe, then writes something to it to wake up the iothread
from the spice server thread to raise an irq. These days qemu bottom
halves can be scheduled from threads and signals, so there is no reason
to do this any more. Time to clean it up.

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.

pci_set_irq and the other pci irq wrappers use
PCI_INTERRUPT_PIN config register to compute device
INTx pin to assert/deassert.
An irq is allocated using pci_allocate_irq wrapper
only if is needed by non pci devices.
Removed irq related fields from state if not used anymore.

The qxl driver expect NULL for QXLRam.memory_configs, but this is never
initialized.
If memory is set to 0xc2c2.., it leads to a spice-critical error when

With a SPICE_DISPLAY_CAP_MONITORS_CONFIG capable client, the client needs to
know what part of the primary to use for each monitor. If the guest driver
does not support this, the server sends messages to the client for a
single monitor spanning the entire primary.
As soon as the guest calls spice_qxl_monitors_config_async once, the server
sets the red_worker driver_has_monitors_config flag and stops doing this.
This is a problem when the driver gets unloaded, for example after a reboot
or when switching to a text vc with usermode mode-setting under Linux.
To reproduce this start a multi-mon capable Linux guest which uses
usermode mode-setting and then once X has started switch to a text vc. Note
how the client window does not only not resize, if you try to resize it
manually you always keep blackborders since the aspect is wrong.
This patch calls a new spice-server method called spice_qxl_driver_unload
which clears the driver_has_monitors_config flag inside the server, thereby
fixing this.

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.

Screendumps are alot simpler as we can update non-active
QemuConsoles now. So we only need to update the QemuConsole
we want write out, then dump the DisplaySurface content into
a ppm file. Done.
No console switching needed. No special support code in the
gfx card emulation needed. Zap it all. Also move ppm_save
out of the vga code and next to the qmp_screendump function.
For now screen dumping is limited to console #0 (like it used
to be), even though it is dead simple to extend it to other
consoles. I wanna finish the console cleanup before setting
new qapi interfaces into stone.

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_*
