qemu_spice_display_init_common() and call it from

Move the wrapper functions which are used by qxl only to qxl.c.
Rename them from qemu_spice_* to qxl_spice_*. Also pass in a
qxl state pointer instead of a SimpleSpiceDisplay pointer.

Surface tracking needs proper locking since it is used from vcpu and spice
worker threads, add it. Also reset the surface counter when zapping all
surfaces.

Add qxl_guest_bug() function which is supposed to be called in case
sanity checks of guest requests fail. It raises an error IRQ and
logs a message in case guest debugging is enabled.
Make PANIC_ON() abort instead of exit. That macro should be used
for qemu bugs only, any guest-triggerable stuff should use the new
qxl_guest_bug() function instead.
Convert a few easy cases from PANIC_ON() to qxl_guest_bug() to
show intended usage.

Since the driver is still in operation even after moving to UNDEFINED, i.e.
by destroying primary in any way.

Some of the QXL port i/o commands are waiting for the spice server to
complete certain actions. Add async versions for these commands, so we
don't block the vcpu while the spice server processses the command.
Instead the qxl device will raise an IRQ when done.
The async command processing relies on an added QXLInterface::async_complete
and added QXLWorker::*_async additions, in spice server qxl >= 3.1

In this case we don't do any operation (i.e. qxl_destroy_primary is a nop,
it checkes d->mode == QXL_MODE_UNDEFINED too) so there will never be an async_complete,
so there will never be a qxl_send_events, so we need to send it now.

no, we want that wen the command is actually complete, on async_complete,
where it is already done.

Ok. Maybe make qxl_destroy_primary return an error in case there is no
primary to destroy, then catch this here? Makes more clear what is
going on here.

That is the cancel code path, i.e. the guest did a async request but we
don't submit one to the spice-server because some sanity check failed,
so we never get a complete callback. Thats why I think we should raise
the QXL_INTERRUPT_IO_CMD interrupt here instead.
cheers,
Gerd

Add two new IOs.
QXL_IO_FLUSH_SURFACES - equivalent to update area for all surfaces, used
to reduce vmexits from NumSurfaces to 1 on guest S3, S4 and resolution change (windows
driver implementation is such that this is done on each of those occasions).
QXL_IO_FLUSH_RELEASE - used to ensure anything on last_release is put on the release ring
for the client to free.

Inform guest drivers about the new features I/O commands we have
now (async commands, S3 support) if building with newer spice, i.e.
if SPICE_INTERFACE_QXL_MINOR >= 1.

Does that actually build with old spice-protocol? I don't think so ...

no, it won't. /me wonders how I did the compilations. I'll use 2 and 3.

That surely belongs into another patch ...

I think we should just not use these defines for now.
In a year or so when the new bits are in widespread use we can raise the
minimum required spice-server+spice-protocol versions, cleanup the ifdef
mess and also use QXL_REVISION_STABLE_V04.
cheers,
Gerd

ok. I'll drop this patch (at least the bits fitting the patch header).
