[libvirt] [PATCH 0/5 0/1 0/1 V3] Add new public API virDomainGetPcpusUsage() and pcpuinfo command in virsh

[Lai Jiangshan]

"virt-top -1" can call virDomainGetPcpusUsage() periodically and get
the CPU activities per CPU. (See the last patch in this series).

virsh is also added a pcpuinfo command which calls virDomainGetPcpusUsage(),
it gets information about the physical CPUs, such as the usage of
CPUs, the current attached vCPUs.

# virsh pcpuinfo rhel6
CPU:            0
Curr VCPU:      -
Usage:          47.3

CPU:            1
Curr VCPU:      1
Usage:          46.8

CPU:            2
Curr VCPU:      0
Usage:          52.7

CPU:            3
Curr VCPU:      -
Usage:          44.1

Changed from V2:
	Simple cleanup
	Add python implementation of virDomainGetPcpusUsage()
