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.
Based on qemu-kvm patch by Lai Jiangshan.

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

Make APICState completely private to apic.c by using DeviceState
in external APIs.
Move apic_init() to pc.c.

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

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.

x86 definitions (especially CPUState uses) prevent many files from
being compiled within libhw.
Move x86 specific declarations (APIC stuff) to a separate file.
