[libvirt] [numatune PATCH v2] Support NUMA tuning

Hi, All This series adopts Daniel's suggestion on v1, using libnuma but not invoking numactl to set the NUMA policy. Add support for "interleave" and "preferred" modes, except the "strict" mode supported in v1. The new XML is like: <numatune> <memory model="interleave" nodeset="+0-4,8-12"/> <numatune> I persist in using the numactl nodeset syntax to represent the "nodeset", as I think the purpose of adding NUMA tuning support is to provide the use for NUMA users, keeping the syntax same as numactl will make them feel better.
