qxl: add optinal 64bit vram bar

This patch adds an 64bit pci bar for vram. It is turned off by default.
It can be enabled by setting the size of the 64bit bar to be larger than
the 32bit bar. Both 32bit and 64bit bar refer to the same memory. Only
the first part of the memory is available via 32bit bar....

qxl: remove flipped

Tested on linux and windows guests. For negative stride, qxl_flip copies
directly to vga->ds->surface->data, for positive it's reallocated to
share qxl->guest_primary.data

qxl: make qxl_render_update async

RHBZ# 747011

Removes the last user of QXL_SYNC when using update drivers that use the
_ASYNC io ports.

The last user is qxl_render_update, it is called both by qxl_hw_update
which is the vga_hw_update_ptr passed to graphic_console_init, and by...

qxl: require spice >= 0.8.2

drop all ifdefs on SPICE_INTERFACE_QXL_MINOR >= 1 as a result,
any check for SPICE_SERVER_VERSION that is now always satisfied,
and SPICE_INTERFACE_CORE_MINOR >= 3 tests, because
0.8.2 has SPICE_INTERFACE_QXL_MINOR 1 and
SPICE_INTERFACE_CORE_MINOR 3....

qxl: add user-friendly bar size properties

Add two properties to specify bar sizes in megabytes instead of bytes,
which is alot more user-friendly.

qxl: stride fixup

spice uses negative stride value to signal the bitmap is upside down.
The qxl renderer (used for scl, vnc and screenshots) wants a positive
value because it is easier to work with. The positive value is then
stored in the very same variable, which has the drawback that the...

qxl: Convert to QEMU thread API

Use QEMU thread API instead of pthread directly. We still need to get
rid of pthread_yield, though, to drop pthread.h inclusion.

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

if SPICE_INTERFACE_QXL_MINOR >= 1.

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.

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: 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....
