Re: [libvirt] [PATCH 09/13] Introduce qemudDomainPinHypervisorFlags and qemudDomainGetHypervisorPinInfo in qemu driver.

Introduce 2 APIs to support hypervisor threads pin in qemu driver.
1) qemudDomainPinHypervisorFlags: setup hypervisor threads pin info.
2) qemudDomainGetHypervisorPinInfo: get all hypervisor threads pin info.
They are similar to qemudDomainPinVcpuFlags and qemudDomainGetVcpuPinInfo.
