[libvirt] [PATCH v5 00/15] CPU Model Baseline and Comparison for s390x

Note: since I've made some changes to a lot of these patches / split up some patches, I've decided to hold off on adding any r-b's in case there is a specific change that someone does not agree with. Changelog: - Properly refactored code from CPU model expansion function - Introduced a cleanup patch for CPU model expansion function - Introduced patches that modifies the refactored code to suit needs for baseline/comparison - CPU expansion function now accepts a virCPUDefPtr - Removed props parsing from CPU model comparison (they weren't used) - Cleaner error reporting when baselining/comparing with erroneous CPU models / features - Various cleanups based on feedback ___ To run these patches, execute the virsh hypervisor-cpu-compare or hypervisor-cpu-baseline commands and pass an XML file describing one or more CPU definition. You can use the definition from virsh domcapabilities or from a guest XML. There is no need extract it from the file and place it a new one, as the XML parser will look specifically for the CPU tags. ___ These patches hookup the virsh hypervisor-cpu-compare/baseline commands for the s390x architecture. They take an XML file describing some CPU definitions and passes the data to QEMU, where the actual CPU model comparison / baseline calculation is handled (available since QEMU 2.8.5). When baselining CPU models with the --features argument, s390x will report a full CPU model expansion. Thanks.
