[libvirt] [PATCH 0/4] Introduce display of IOThreads Information

These patches satisfy part of: https://bugzilla.redhat.com/show_bug.cgi?id=1135491 Patches 1 and 2 are fairly straightforward adding a new API type patches although they were implemented with the thought of how patch 3 works. Also rather than implement a get iothreads and a get iothreadspin API, I combined the two into one. I could separate if that's more desirable, but it just seemed more natural to have one API do both. Patch 3 adds the qemu related to code to fetch not only the IOThreads data, but also the cpumap/cpumaplen in order to display the CPU Affinity. For that I somewhat followed how the vcpuinfo code works, but also a bit on how the nodecpumap code does things. Unlike the vcpuinfo code, I had no way to count the IOThreads before calling, so rather than pass in a cpumap/cpumaplen - I allocated them in the qemu code and passed them back within the IOThreadsInfo structure. Of course it did get me to thinking why are we doing 1 for each IOThread, but to that degree I was following the vcpu model. Patch 4 is the new 'virsh iothreads' command with no arguments (for now). It will display the IOThreads of active domains only. "Future" patches will implement a SetIOThreads API to change the thread pinning and allow for add/delete of IOThreads. I'm hoping to use the same command with new options --pin && --cpuset for pinning the IOThreads or --add/--del to add/remove IOThreads, but I wanted to make sure I had buyin on the use of one API to accomplish both get of basic IOThread data and CPU Affinity data.
