target-i386: move cpu halted decision into x86_cpu_reset

MP initialization protocol differs between cpu families, and for P6 and
onward models it is up to CPU to decide if it will be BSP using this
protocol, so try to model this. However there is no point in implementing...

apic: Defer interrupt updates to VCPU thread

KVM performs TPR raising asynchronously to QEMU, specifically outside
QEMU's global lock. When an interrupt is injected into the APIC and TPR
is checked to decide if this can be delivered, a stale TPR value may be...

i386 hw/: Don't use CPUState

Scripted conversion:

sed -i "s/CPUState/CPUX86State/g" $file
done

target-i386: Add infrastructure for reporting TPR MMIO accesses

This will allow the APIC core to file a TPR access report. Depending on
the accelerator and kernel irqchip mode, it will either be delivered
right away or queued for later reporting.

In TCG mode, we can restart the triggering instruction and can therefore...

apic: Inject external NMI events via LINT1

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...

apic: Introduce apic_report_irq_delivered

The in-kernel i8259 and IOAPIC backends for KVM will need this, so
encapsulate the shared bits.

apic: Factor out base class for KVM reuse

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...

target-i386: Remove unused polarity arguments from APIC API

Polarity of external interrupts needs to be handled in the IOAPIC.
Passing it to the APIC is pointless. So remove all these arguments.

apic: qdev conversion cleanup

Make APICState completely private to apic.c by using DeviceState
in external APIs.

Move apic_init() to pc.c.

apic: convert to qdev

Convert to qdev.

Use an opaque CPUState pointer because of missing VMState
implementation for CPUState.

apic: avoid using CPUState internals

Move the actual CPUState contents handling to cpu.h and cpuid.c.

Handle CPU reset and set env->halted in pc.c.

Add a function to get the local APIC state of the current
CPU for the MMIO.

ioapic: unexport ioapic_set_irq

There's no need to use ioapic_set_irq() outside of ioapic.c, so
make it static.

Move x86 specific PC declarations to a separate file

x86 definitions (especially CPUState uses) prevent many files from
being compiled within libhw.

Move x86 specific declarations (APIC stuff) to a separate file.
