This series is based on the previous patchset from Chen Fan:
https://lists.nongnu.org/archive/html/qemu-devel/2014-05/msg02360.html
We try to make cpu hotplug with device_add, and make
"-device foo-x86_64-cpu" available, also we can set apic-id
property with command line, if without setting apic-id property,
we offer the first unoccupied apic id as the default new apic id.
When hotplug cpu with device_add, additional check of APIC ID will be
done after cpu object initialization which was different from
'cpu_add' command that check 'ids' at the beginning.
The is the first half of the previous series:
[RFC V2 00/10] cpu: add device_add foo-x86_64-cpu and i386 cpu hot remove
support

Changelog since v3:
-fix cross version migration issue
-drop ICC bus impl
-do a generic for apic to send gpe event
-do not use migration code for CONFIG_USER_ONLY target
Changelog since v2:
-rebase on latest upstream.
-add cpu instance finalize.
Changelog since v1:
-rebased on latest upstream.
-introduce a help function to hide the access to icc_bus.
-use a macro ACPI_ID_NOT_SET to replace the magic number(0xFFFFFFFF).
Changelog since RFC:
-split out APIC vmstate/QMP-monitor changes into separate patches.
-add the handle of the startup cpus(-device foo).
-remove duplicated checking about env->cpuid_apic_id.
-do actual APIC ID allocation at realize time if it is not set before.
-remove the unneeded x86_cpu_cpudef_instance_init().
-split off device_del support out here.
