Since 39bffca203 (qdev: register all
types natively through QEMU Object Model), TypeInfo as used in
the common, non-iterative pattern is no longer amended with information
and should therefore be const.
Fix the documented QOM examples:
sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h
Since frequently the wrong examples are being copied by contributors of
new devices, fix all types in the tree:
sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c
sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c
This also avoids to piggy-back these changes onto real functional
changes or other refactorings.

The devram memslot stays active when qxl enters UNDEFINED mode (i.e, no
primary surface). If migration has occurred while the device is in
UNDEFINED stae, the memslots have to be reloaded at the destination.

Register displaychangelistener last, after spice is fully initialized,
otherwise we may hit NULL pointer dereferences when qemu starts calling

When entering vga mode the display size likely changes,
notify all displaychangelisteners about this.
Probably went unnoticed for a while as one if the first
things the guest does after leaving qxl native mode and
entering qxl vga mode is to set the vga video mode. But
there is still a small window where qemu can operate on
stale data, leading to crashes now and then.

Due to usage of pixman for rendering on all spice surfaces we have
pixman's requirement that the stride be word aligned. A guest not
honoring that can crash spice and qemu with it due to failure to create
a surface (in spice-server). Avoid this early on in primary surface
creation and offscreen surface creation.
Recently windows guests got odd width support which triggers a non word
aligned primary surface in 16bit color depth. Off screen surfaces have
always been word aligned, but doesn't hurt to check them here too.

Stop abusing displaysurface fields for text mode displays.
(bpp = 0, width = cols, height = lines).
Add flags to displaystate indicating whenever text mode display
(curses) or gfx mode displays (sdl, vnc, ...) are present.
Add separate displaychangelistener callbacks for text / gfx mode
resize & updates.
This allows to enable gfx and txt diplays at the same time and also
paves the way for more cleanups in the future.

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are

With the next qemu version (1.3) we are going to bump the qxl device
revision to 4. The new features available require a recent spice-server
version, so raise up the bar. Otherwise we would end up with different
qxl revisions depending on the spice-server version installed, which
would be a major PITA when it comes to compat properties.

Until now we used only the agent to change the monitor count and each
monitor resolution. This patch introduces the qemu part of using the
device as the mediator instead of the agent via virtio-serial.
Spice (>=0.11.5) calls the new QXLInterface::client_monitors_config,
which returns wether the interrupt is enabled, and if so and given a non
NULL monitors config will
generate an interrupt QXL_INTERRUPT_CLIENT_MONITORS_CONFIG with crc
checksum for the guest to verify a second call hasn't interfered.
The maximal number of monitors is limited on the QXLRom to 64.

The recent introduction of set_client_capabilities has broken
(seamless) migration by trying to call qxl_send_events pre (seamless
incoming) and post (*) migration, triggering the following assert:
qxl_send_events: Assertion `qemu_spice_display_is_running(&d->ssd)' failed.
The solution is easy, pre migration the guest will have already received
the client caps on the migration source side, and post migration there no
longer is a guest, so we can simply ignore the set_client_capabilities call
in both those scenarios.
*) Post migration, so not fatal for to the migration itself, but still a crash

Zap the global VGA_RAM_SIZE #define, make the vga ram size configurable
for standard vga and vmware vga. cirrus and qxl are left with a fixed
size (and private VGA_RAM_SIZE #define) for now.
qxl needs some non-trivial adjustments in the mode list handling deal
with a runtime-configurable size, which calls for a separate qxl patch.
cirrus emulates cards which have 2 MB (isa) and 4 MB (pci), so I guess
it would make sense to use these sizes. That change would break
migration though, so I left it fixed at 8 MB size. Making it
configurabls is pretty pointless for cirrus as we have to match real
hardware.
