[libvirt] [PATCH for 4.6.0 0/3] Revert VIR_AUTOPTR work in cgroup

[Michal Privoznik]

Turns out, our code relies on virCgroupFree(&var) setting
var = NULL. Otherwise a double free can occur:

Rather than inserting var = NULL after each virCgroupFree() call lets
revert the patches. The ideal solution would be to use virCgroupFree
both directly and as attribute cleanup.

Michal Prívozník (3):
  Revert "util: cgroup: use VIR_AUTOPTR for aggregate types"
  Revert "util: cgroup: define cleanup function using
    VIR_DEFINE_AUTOPTR_FUNC"
  Revert "util: cgroup: modify virCgroupFree to take virCgroupPtr"
