This patch enables dirty log tracking whenever it's needed and disables it
when it is not.
We unconditionally enable dirty log tracking on reset, restart dirty log
tracking when PCI IO regions are remapped, and disable/enable it based on
commands from the guest.

VMware VGA requires that the depth presented to the guest is the same as the
DisplaySurface that it renders to. This is because it performs a very simple
memcpy() to blit from one surface to another.
We currently hardcode a 24-bit depth. The surface allocator for SDL may, and
usually will, allocate a surface with a different depth causing screen
corruption.
This changes the code to allocate the DisplaySurface before initializing the
device which allows the depth of the DisplaySurface to be used instead of
hardcoding something.

Apparently, VBE maps the VGA vram to a fixed physical location. KVM requires
that all mappings of the VGA vram have dirty tracking enabled on them. Any
access to the VGA vram through the VBE mapping currently fails to result in
dirty page tracking updates causing a black screen.
This is the true root cause of VMware VGA not working correctly under KVM and
likely also an issue with some of the std-vga black screen issues too.
Cirrus does not enable VBE so it would not be a problem when using Cirrus.

Add a error message in case we fail to parse a qdev property.
Also make qemu not abort() in case setting a global property can't be
set. This used to be a clear programming error. The introduction of
the -global switch changed that though, so better exit instead (after
printing the new error message).

The multiboot implementation assumed that there is only one program header

Currently we always set the "config space changed" bit to 1 when triggering
any virtio interrupt. While that worked in 2.6.27, newer kernels interpret
that value as "only the config space changed and nothing else happened".
Since we usually trigger interrupts to tell the guest that something did
happen, we just not tell it the config space changed for now until we
implement the correct callback for that.

This patch fills the DriveInfo->unit after hotplugging a scsi disk.
It makes a difference when auto-assigning a scsi id, where unit was

Current PCI code will simply hw_error() and thus abort in case no free
PCI slot is available or the requested PCI slot is already in use by
another device. For the hotplug case this behavior is not acceptable.
This patch makes qemu pass up the error properly, so the calling code
can decide whenever it wants to exit with an error (on startup) or
whenever it wants to continue (hotplug).

The PCI bus on x86 requires ACPI for hotplug support, thus disbling ACPI
also disables hotplug for the PCI bus. This patch makes qemu check
whenever the PCI bus in question can handle hotplug before trying to add
devices. This is needed because qdev will abort() on any attempt to
hotplug devices into a non-hotpluggable bus.

All "normal" system emulation targets in qemu I'm aware of display
output on either VGA or serial output.
Our S390x virtio machine doesn't have such kind of legacy hardware. So
instead we need to default to a virtio console.
Add flags to QEMUMachine to indicate which kind of default devices make
sense for the machine in question. Use it for S390x: enable virtcon,
disable serial, parallel and vga.

On hosts without high-res timers it is impossible to inject rtc interrupt
faster then 1kHz. Windows sometimes configures RTC to generate 1kHz
interrupts, so we can't inject missed interrupts when running on such
hosts. Always injecting an interrupt on REG_C read is also not an option
since Windows wait for REG_C to become zero with interrupt disabled
during boot. This patch uses mixed approach: accelerate timer + inject
up to 1000 interrupts on REG_C read.
