Ryota Ozaki c8c9ef2757 lxc: suspend/resume support
* src/conf/domain_conf.c: Don't assume all virDomainObjPtr have
  a non-NULL monitor_chr field in virDomainObjFormat.
* src/lxc/lxc_driver.c: Implement suspend/resume driver APis
* src/util/cgroup.c, src/util/cgroup.h: Support the 'freezer'
  cgroup controller
* src/libvirt_private.syms: Export virCgroupSetFreezerState
  and virCgroupGetFreezerState
