0caa2d3992 libcontainer: Don't use UsetCloseOnExec, it is racy 
We can't keep file descriptors without close-on-exec except with
syscall.ForkLock held, as otherwise they could leak by accident into
other children from forks in other threads.

Instead we just use Cmd.ExtraFiles which handles all this for us.

This fixes https://github.com/dotcloud/docker/issues/4493

88aed3bf92 libcontainer: Use MS_PRIVATE instead of MS_SLAVE 
Now that we unmount all the mounts from the global namespace we can
use a private namespace rather than a slave one (as we have no need
for unmounts of inherited global mounts to propagate into the
container).

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.
