apic: qdev conversion cleanup
Make APICState completely private to apic.c by using DeviceStatein external APIs.
Move apic_init() to pc.c.

apic: convert to qdev
Convert to qdev.
Use an opaque CPUState pointer because of missing VMStateimplementation 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 currentCPU for the MMIO.
apic: avoid passing CPUState from CPU code
Pass only APICState when accessing APIC from CPU code.
apic: avoid passing CPUState from devices
Pass only APICState from pc.c.
apic: improve debugging
Add a DPRINTF macro. Use TARGET_FMT_plx for printing target_phys_addr_titems. Add a separate flag for debugging coalescing interrupts.
Move x86 specific PC declarations to a separate file
x86 definitions (especially CPUState uses) prevent many files frombeing compiled within libhw.
Move x86 specific declarations (APIC stuff) to a separate file.
KVM: Rework VCPU state writeback API
This grand cleanup drops all reset and vmsave/load relatedsynchronization points in favor of four(!) generic hooks:

There is absolutely no need to call reset functions when initializingdevices. Since we are already registering them, calling qemu_system_reset()should suffice. Actually, it is what happens when we reboot the machine,...

don't call cpu_sychronize_state from reset handlers
Doing this will make the vcpu ioctl be issued from the I/O thread, insteadof cpu thread. The correct behaviour is to call it from within the cpu thread,as soon as we are ready to go.
