Merge remote-tracking branch 'remotes/afaerber/tags/qom-cpu-for-2.0' into staging

QOM CPUState refactorings / X86CPU

* Deadlock fix for exit requests around CPU reset
* X86CPU x2apic for KVM
* X86CPU model subclasses
* SPARCCPU preparations for model subclasses
* -cpu arguments for arm, cris, lm32, moxie, openrisc, ppc, sh4, uc32
* m68k assertion cleanups
* CPUClass hooks for cpu.h inline functions
* Field movements from CPU_COMMON to CPUState and follow-up cleanups
