Merge remote-tracking branch 'remotes/cohuck/tags/s390x-20180301-v2' into staging

- add query-cpus-fast and deprecate query-cpus, while adding s390 cpu
  information
- remove s390x memory hotplug implementation, which is not useable in
  this form
- add boot menu support in the s390-ccw bios
- expose s390x guest crash information
- fixes and cleaups
