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.

Change breakpoint_invalidate() argument to CPUState alongside.
Since all targets now assign a softmmu-only field, we can drop helpers
cpu_class_set_{do_unassigned_access,vmsd}() and device_class_set_vmsd().
Prepares for changing cpu_memory_rw_debug() argument to CPUState.

This adds support for GDB's c addr (Continue) and s addr (Single Step).
Prepares for dropping cpu_pc_from_tb().

x86 was using additional CPU_DUMP_* flags, so make that configurable in
CPUClass::reset_dump_flags.
This adds reset logging for alpha, unicore32 and xtensa.

Since commit 878096eeb278a8ac1ccd6667af73e026f29b4cf5 (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.

This allows to move the call into CPUState's realizefn.
Therefore move the stub into libqemustub.a.

Register the CPU VMState in the correct way, via cpu_class_set_vmsd(),
rather than doing it in two different wrong ways (once by providing
cpu_save and cpu_load functions, and once by setting the vmsd field in
DeviceClass).

The value of "do_interrupt" member of CPUClass shoule be set to a
target-specific function, or it will lead to a segfault like below:
$ moxie-softmmu/qemu-system-moxie -M moxiesim
