[libvirt] [PATCHv10 0/4] Introduce x86 Cache Monitoring Technology (CMT)

These patches are the remaining part for the CMT enabling series,
and most of the series have been merged.

This series is addressing John's review comments and suggestions,
which are

Change lists:
Changes in v10:
-. Add tag (virResctrlMonitorType) in qemuDomainGetResctrlMonData, thus
   qemuDomainGetResctrlMonData could be reused for MBM.
-. Using VIR_APPEND_ELEMENT to append virQEMUResctrlMonDataPtr list.
-. Add qemuDomainFreeResctrlMonData.
-. Add virResctrlMonitorFreeStats.
-. Return a list of virResctrlMonitorStatsPtr instead of
   a virResctrlMonitorStats array in virResctrlMonitorGetStats.

Changes in V9:
-. Addressing code review comments form John.
-. Refined the names for new data structure and new functions.
-. Merged qemuDomainGetStatsCpuResMonitorPerTag and qemuDomainGetStatsCpuResMonitor,
   and refined new function name based on the fact that we only support cache monitor now.
Wang Huaqiang (4):
  util: Return a list of pointer in virResctrlMonitorGetStats
  util: Add function to free monitor statistical data
  qemu: Report cache occupancy (CMT) with domstats
