It the same commit, a working hmp_cpu was implemented. Since then, no further changes were made in qmp_cpu, resulting now in a working 'cpu' command that works in HMP and a 'cpu' command in QMP that does nothing. Regardless of what constraints were involved that time in not implemeting qmp_cpu, at this moment it is possible to have both. This patch brings the logic of hmp_cpu to qmp_cpu and converts the HMP function to use its QMP counterpart.
