QOM CPUState refactorings / X86CPU

* Conversion of global CPU list to QTAILQ - preparing for CPU hot-unplug
* Document X86CPU magic numbers for CPUID cache info

* afaerber/tags/qom-cpu-for-anthony:
  target-i386: Use #defines instead of magic numbers for CPUID cache info
  cpu: Replace qemu_for_each_cpu()
  cpu: Use QTAILQ for CPU list
  a15mpcore: Use qemu_get_cpu() for generic timers
