Convert all vga memory to the memory API. Note we need to fall back to
get_system_memory(), since the various buses don't pass the vga window
as a memory region.
We no longer need to sync the dirty bitmap of the cirrus mapped memory
banks, since the memory API takes care of that for us.

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.

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

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.

We don't use qemu internals from spice server context any more.
Thus we don't also need to grab the iothread mutex from spice
server context. And we don't have to temporarely release the

This patch moves the creation of spice screen updates from the spice
server context to qemu iothread context (display refresh timer to be
exact). This way we avoid accessing qemu internals (display surface)
from spice thread context which in turn allows us to simplify locking.

Live migration from and to spice 0.4 qxl devices isn't going to work.
Rip out the bits which attempt to support that. Zap the subsection
logic which is obsolete now. Bumb the version to make a clean cut.

qxl is a paravirtual graphics card. The qxl device is the bridge
between the guest and the spice server (aka libspice-server). The
spice server will send the rendering commands to the spice client, which
will actually render them.
The spice server is also able to render locally, which is done in case
the guest wants read something from video memory. Local rendering is
also used to support display over vnc and sdl.
qxl is activated using "-vga qxl". qxl supports multihead, additional
cards can be added via '-device qxl".
