[CRIU] [PATCHv0 0/3] Support C/R of frozen cgroup

[Eugene Batalov]

Hello. This patchset implements c/r of ps tree
that was frozen using freezer controller before start of
ps tree dumping.
Such ps tree will be frozen after restore.
This means that we can c/r paused Docker containers.
See details in issue #20 on github:
https://github.com/xemul/criu/issues/20

We'll send patch with autotest for this feature later.

>From user point of view we extend functionality of --freeze-cgroup
option so CRIU documentation and help message for --freeze-cgroup
option may need some improvement/clarification.
