c5f3dabba9 qxl: unbreak after memory API conversion
Break is only noticable with newer spice-server library (0.8.2 release
or 0.9.0 and newer on master branch).

ioport_write's val was changed from uint32_t to uint64_t, this
broke two printfs. Use PRId64 instead of %d.

be48e99512 qxl: allowing the command rings to be not empty when spice worker is stopped RHBZ #728984
same as 8927cfbba2, but for qxl_check_state, that was
triggered by qxl_pre_load (which calls qxl_hard_reset, which calls qxl_soft_reset),
and caused the migration target to crash.

b195043003 vga: convert vga and its derivatives to the memory API
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.

[jan: fix vga-pci logging]

3e16b9c534 qxl: add QXL_IO_FLUSH_{SURFACES,RELEASE} for guest S3&S4 support
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.

5ff4e36c80 qxl: async io support using new spice api
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

2bce040057 qxl: error handling fixes and cleanups.
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.

a19cbfb346 spice: add qxl device
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".

[ v2: add copyright to files                     ]
[ v2: use qemu-common.h for standard includes    ]
[ v2: create separate qxl-vga device for primary ]
