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...

qxl: bump pci rev

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.

sneaked in some 81+ column line spliting.

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....

spice/qxl: move worker wrappers

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.

qxl: fix surface tracking & locking

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.

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...

spice/qxl: zap spice 0.4 migration compatibility bits

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logic which is obsolete now.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....

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....
