Split up the IOAPIC analogously to APIC and i8259. KVM will share the
IOAPICCommonState, the vmstate, reset logic and certain init parts with
the user space model.

As all devices undergo a reset prior to vmloa, and the reset value of
irr is 0, we do not need to do this clearing for older vmstates
explicitly. Dropping this redundant code will also make KVM integration
a bit simpler.

Analogously to the APIC, we will reuse some parts of the user space
i8259 model for KVM. The base class provides a common device state, the
vmstate, the property list, a reset core and some shared init bits.

This also introduces a common helper to instantiate a single i8259 chip
from the cascade-creating i8259_init function.

Use DeviceState instead of PicState in the public i8259 API. This is
cleaner and allows to reorganize the PIC data structures for KVM reuse.

To enable migration between accelerated and non-accelerated APIC models,
we will need to handle the timer saving and restoring specially and can
no longer rely on the automatics of VMSTATE_TIMER. Specifically,
accelerated model will not start any QEMUTimer.

This patch therefore factors out the generic bits into apic_next_timer
and use a post-load callback to implemented model-specific logic.

The KVM in-kernel APIC model will reuse parts of the user space model
while providing the same frontend view to guest and most management
interfaces.

Factor out an APIC base class to encapsulate those parts that will be
shared by user space and KVM model. This class offers callback hooks for
init, base/tpr setting, and the external NMI delivery that will be
set via APICCommonInfo structure and implemented specifically in the
subclasses.

The in-kernel i8259 and IOAPIC backends for KVM will need this, so

On real hardware, NMI button events are injected via the LINT1 line of
the APICs. E.g. kdump expect this wiring and gets upset if the per-APIC
LINT1 mask is not respected, i.e. if NMIs are injected to VCPUs that
should not receive them. Change the APIC emulation code to reflect this.

All LVTs are masked on reset, so the timer becomes ineffective. Letting

QEMU does have a "scsi" option (to be used like -device
virtio-blk-pci,drive=foo,scsi=off).  However, it only
masks the feature bit, and does not reject the command
if a malicious guest disregards the feature bits and
issues a request.

Without this patch, using scsi=off does not protect you
from CVE-2011-4127.
