The timer was deadlocking when the interval was set too low. It would cause a
flood of timer events and the CPU would halt indefinately. This is a known issue
and theres a generic workaround in place in ptimer on ptimer_set_limit(),
however the Xilinx timer uses ptimer_set_count() instead of set_limit. Changed
the call to set_count() to an equivalent call of set_limit() instead, which
brings the workaround into play.

QEMU exposes its version to the guest's hardware and in some cases that is wrong
(e.g. Windows prints messages about driver updates when you switch
the QEMU version).
There is a new field now on the struct QEmuMachine, hw_version, which may
contain the version that the specific machine should report. If that field is
set, then that machine will report that version to the guest.

This patch adds two things. First it allows QEMU to distinguish between
regular powerdown and S4 powerdown. Later separate QMP notification will
be added for S4 powerdown. Second it allows S3/S4 states to be disabled
from QEMU command line. Some guests known to be broken with regards to
power management, but allow to use it anyway. Using new properties
management will be able to disable S3/S4 for such guests.
Supported system state are passed to a firmware using new fw_cfg file.
The file contains 6 byte array. Each byte represents one system
state. If byte at offset X has its MSB set it means that system state
X is supported and to enter it guest should use the value from lowest 3

Some of the virtio devices have the same frontend name, but actually
implement different devices behind the scenes through aliases.
The indicator which device type to use is the architecture. On s390, we
want s390 virtio devices. On everything else, we want PCI devices.
Reflect this in the alias selection code. This way we fix commands like
-device virtio-blk on s390x which with this patch applied select the
correct virtio-blk-s390 device rather than virtio-blk-pci.

Now that global properties do not depend on buses anymore, set

Signed-off-by: Andreas Färber <afaerber@suse.de>
In qdev, each bus in practice identified an abstract superclass, but
this was mostly hidden. In QOM, instead, these abstract classes are
explicit so we can move bus properties there.
All bus property walks are removed, and all device property walks
are changed to look along the class hierarchy instead.
We would have duplicates if class A defines some properties and its
subclass B does not define any, because class_b->props will be
left equal to class_a->props.
The solution here is to reintroduce the class_base_init TypeInfo
callback, that was present in one of the early QOM versions but
removed (on my request...) before committing.
This breaks global bus properties, an obscure feature when used
with the command-line which is actually useful and used when used by
backwards-compatible machine types. So this patch also adjusts the
global bus properties in hw/pc_piix.c to refer to the abstract class.
Globals and other properties must be modified in the same patch to
avoid complications related to initialization ordering.

After setting a balloon target value, applications have to
continually poll 'query-balloon' to determine whether the
guest has reacted to this request. The virtio-balloon backend
knows exactly when the guest has reacted though, and thus it
is possible to emit a JSON event to tell the mgmt application
whenever the guest balloon changes.
This introduces a new 'qemu_balloon_changed()' API which is
to be called by balloon driver backends, whenever they have
a change in balloon value. This takes the 'actual' balloon
value, as would be found in the BalloonInfo struct.
The qemu_balloon_change API emits a JSON monitor event which
looks like:
{"timestamp": {"seconds": 1337162462, "microseconds": 814521},
"event": "BALLOON_CHANGE", "data": {"actual": 944766976}}

Due to a offset between the clock used to generate the in-kernel
count_load_time (CLOCK_MONOTONIC) and the clock used for processing this
in userspace (vm_clock), reading back the output of PIT channel 2 via
port 0x61 was broken. One use cases that suffered from it was the CPU
frequency calibration of SeaBIOS, which also affected IDE/AHCI timeouts.
This fixes it by calibrating the offset between both clocks on
kvm_pit_get and adjusting the kernel value before saving it in the
userspace state. As the calibration only works while the vm_clock is
running, we cache the in-kernel state across stopped phases.

Legacy (non-pvops) gntdev drivers may require this to be done when the
number of grants intended to be used simultaneously exceeds a certain
driver specific default limit.

kvm_put_apic_state's attempt to clear *kapic before setting its
bits cleared sizeof(void*) bytes (no more than 8) rather than the
intended 1024 (KVM_APIC_REG_SIZE) bytes. Spotted by coverity.

In particular this simplifies the &s->mpu->cpu->env expression again.
first_cpu and ->next_cpu are expected to be QOM'ified later.
