Commit c643bed99 moved qemu_init_vcpu() calls to common CPUState code.
This causes x86 cpu-add to fail with "KVM: setting VAPIC address failed".
The reason for the failure is that CPUClass::kvm_fd is not yet
initialized in the following call graph:
->x86_cpu_realizefn
->x86_cpu_apic_realize
->qdev_init
->device_set_realized
->device_reset (hotplugged == 1)
->apic_reset_common
->vapic_base_update
->kvm_apic_vapic_base_update
This causes attempted KVM vCPU ioctls to fail.
By contrast, in the non-hotplug case the APIC is reset much later, when
the vCPU is already initialized.
As a quick and safe solution, move the qemu_init_vcpu() call back into
the targets' realize functions.

Since commit 878096eeb2 (cpu: Turn
cpu_dump_{state,statistics}() into CPUState hooks) CPUArchState is no
longer needed.
Add documentation and make the functions available through qemu/log.h
outside NEED_CPU_H to allow use in qom/cpu.c. Moving them to qom/cpu.h
was not yet possible due to convoluted include paths, so that some
devices grow an implicit and unneeded dependency on qom/cpu.h for now.

Commit 478032a93d (target-openrisc:
Rename CPU subtypes) suffixed CPU sub-types with "-or32-cpu" but forgot
to update openrisc_cpu_class_by_name(), so that it was still looking for
the types without suffix.
Make target-openrisc running OK by adding the suffix to the model name.
This means it is no longer possible to use -cpu or1200-or32-cpu or
-cpu any-or32-cpu though.

The target-specific ENV_GET_CPU() macros have allowed us to navigate
from CPUArchState to CPUState. The reverse direction was not supported.
Avoid introducing CPU_GET_ENV() macros by initializing an untyped
pointer that is initialized in derived instance_init functions.
The field may not be called "env" due to it being poisoned.

Model names were mapped 1:1 to type names. As a side effect this
registered a type "any", which is now a device.
To avoid "-device any" silliness and to pave the way for compiling
multiple targets into one executable, adopt a <name>-<arch>-cpu scheme.
No functional changes for -cpu arguments or -cpu ? output.

A basic assumption of CPU subtypes is that only specific models get
instantiated. A user is not supposed to instantiate an <arch>-cpu.
Suppress it via abstract = true, which also drops or32-cpu from

If the name matches an existing type, also check whether that type is
