[libvirt] [PATCHv2 00/11] bulk stats: QEMU implementation

This patchset enhances the QEMU support for the new bulk stats API to include equivalents of these APIs: virDomainBlockInfo virDomainGetInfo - for balloon stats virDomainGetCPUStats virDomainBlockStatsFlags virDomainInterfaceStats virDomainGetVcpusFlags virDomainGetVcpus This subset of API is the one oVirt relies on. Scale/stress test on an oVirt test environment is in progress. changes in v2: polishing and optimizations. - incorporated feedback from Li Wei (thanks) - added documentation - optimized block group to gather all the information with just one call to QEMU monitor - stripped to bare bones merged the 'block info' group into the 'block' group - oVirt actually needs just one stat from there - reorganized the keys to be more consistent and shorter. The patchset is organized as follows: - the first 4 patches do refactoring to extract internal helper functions to be used by the old API and by the new bulk one. For block stats on helper is actually added instead of extracted. - since some groups require access to the QEMU monitor, one patch extend the internal interface to easily accomodate that - finally, the last six patches implement the support for the bulk API.
