This series applies on top of 'part2' fetch everything from my repo:

  git fetch https://gitlab.com/pipo.sk/libvirt.git ppc-send

In this part:
 - caps code is refactored to simplify error paths
 - vircapstest is removed
 - qemumemlocktest is converted to use real caps
 - qemuhotplugtest is converted to use real caps
 - ppc64 fake caps invocation is dropped from qemuxml2xml/argv tests
 - always present ppc64 caps are drooped
 - ppc64 fake emulators are removed

Peter Krempa (31):
