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.

48cfa0fbdf runtime: Fix unique constraint error checks
The sqlite3 version in fedora (3.8) returns a different error string in the unique constraints
failure case than the one in hack/ (3.7). This updates the check to detect both, fixing
one integration check failure on Fedora.
