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.

Support hairpin NAT without going through docker server
...
Hairpin NAT is currently done by passing through the docker server. If
two containers on the same box try to access each other through exposed
ports and using the host IP the current iptables rules will not match the
DNAT and thus the traffic goes to 'docker -d'
This change drops the restriction that DNAT traffic must not originate
from docker0. It should be safe to drop this restriction because the
DOCKER chain is already gated by jumps that check for the destination
address to be a local address.

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.
