We place the actual image/containers in the "rootfs" directory, which
allows us to have other data in the toplevel directory in the mount.
For starters, this means the "lost+found" directory from mkfs will
not always be in your container/image.
Secondly, we can create a file "id" in the toplevel dir which is not
visible from the container. This is useful because it allows us to map
back from the device fs to the container if something goes wrong with
the devicemapper metadata.

This will try to move the directories that were
previously symlinked until a full migration is complete.

It makes no sense to use the aufs or devicemapper drivers for volumes.
The aufs one is perhaps not a big problem, but the devicemapper one
certainly is. It will be unnecessarily using a dm
blockdevice-over-loopback with a limited size base FS.
This just hardcodes the driver to be the dummy, perhaps in the future
we can have other drivers that make sense for the volumes.

This adds a generic Status call in the Driver api and
implements if for the devicemapper backend.
The status is an array of key/value strings rather than a map so that
we can guarantee some static order of the docker info output.

to force the drivers to implement the methods

This moves the Diff() operation to a separate Differ interface and
implements a fallback that uses the Changes() results to encode
a diff tar.
