[libvirt] [PATCH v2 0/5] cgroup refactor



This series refactors cgroup code to:

  - provide lazy creation of cgroup directories, despite of what
    level they are.
  - remove cgroup directories if no one is using the corresponding
    virCgroup.

This series is splitted in a manner for easier review. Patch 2 is
the main implementation. Patch 3, 4, 5 should have been squashed
into one in order to build, but harder to review.

Hu Tao (5):
  refactor virCgroupDetectMounts and virCgroupDetectPlacement
  cgroup: refactor virCgroup
  cgroup: replace old cgroup
  qemu: replace old cgroup
  lxc: replace old cgroup
