hw/i386/x86: Fix PIC interrupt handling if APIC is globally disabled
QEMU populates the apic_state attribute of x86 CPUs if supported by real hardware or if SMP is active. When handling interrupts, it just checks whether apic_state is populated to route the interrupt to the PIC or to the APIC. However, chapter 10.4.3 of [1] requires that:
When IA32_APIC_BASE[11] is 0, the processor is functionally equivalent to an IA-32 processor without an on-chip APIC.
This means that when apic_state is populated, QEMU needs to check for the MSR_IA32_APICBASE_ENABLE flag in addition. Implement this which fixes some real-world BIOSes.

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 MP initialization protocol in qemu. Thus first CPU is always marked as BSP.
This patch: - moves decision to designate BSP from board into cpu, making cpu self-sufficient in this regard. Later it will allow to cleanup hw/pc.c and remove cpu_reset and wrappers from there. - stores flag that CPU is BSP in IA32_APIC_BASE to model behavior described in Inted SDM vol 3a part 1 chapter 8.4.1 - uses MSR_IA32_APICBASE_BSP flag in apic_base for checking if cpu is BSP

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 used, causing spurious interrupts in the end.
Fix this by deferring apic_update_irq to the context of the target VCPU. We introduce a new interrupt flag for this, CPU_INTERRUPT_POLL. When it is set, the VCPU calls apic_poll_irq before checking for further pending interrupts. To avoid special-casing KVM, we also implement this logic for TCG mode.

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 forward the event directly. KVM does not allows us to restart, so we postpone the delivery of events recording in the user space APIC until the current instruction is completed.
Note that KVM without in-kernel irqchip will report the address after the instruction that triggered the access.

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 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.

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

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 should not receive them. Change the APIC emulation code to reflect this.
Based on qemu-kvm patch by Lai Jiangshan.

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