83de20deb7 libcontainer: Use pivot_root instead of chroot 
Instead of keeping all the old mounts in the container namespace and
just using subtree as root we pivot_root so that the actual root in
the namespace is the root we want, and then we unmount the previous
mounts.

This has multiple advantages:

* The namespace mount tree is smaller (in the kernel)
* If you break out of the chroot you could previously access the host
  filesystem. Now the host filesystem is fully invisible to the namespace.
* We get rid of all unrelated mounts from the parent namespace, which means
  we don't hog these. This is important if we later switch to MS_PRIVATE instead
  of MS_SLAVE as otherwise these mounts would be impossible to unmount from the
  parent namespace.

3de41b34a2 libcontainer: Initial version of cgroups support 
This is a minimal version of raw cgroup support for libcontainer.
It has only enough for what docker needs, and it has no support
for systemd yet.
