[Qemu-devel] [PATCH 03/21] introduce cpu_resume(), for single CPU |

also add stub for it, to make possible to use it in qom/cpu.c,
which is shared with user emulators.

v2:
* rename resume_vcpu() to cpu_resume()
* remove comment about neccessity to call cpu_synchronize_post_init()
which is applicable only to CPU creation. But not to generic CPU
resume.
Note:
it will be re-used from qom/cpu.c by hotpluged CPU
