On systems that supports reflinking (i.e. btrfs) this means the dummy
backend is much faster at copying files and will be sharing file data in
a CoW fashion.
On my (btrfs) system this makes "docker run ubuntu echo hello world" go
from about 3 seconds to about 1 second. Not instant, but clearly better.
cp --reflink=auto is availible since coreutils 7.5 (around 2009), so this
seems pretty ok to rely on.
cp is also better at preserving file metadata than tar, so for instance
it will copy xattrs.

This change makes docker compute container size correctly.
The old code isn't taking hard links into account. Containers could
seem like they're up to 1-1.5x larger than they really were.

This moves Driver.Size() to Differ.DiffSize(), removing the empty
implementations in devmapper and dummy, and renaming the one in aufs.
Then we fall back to a container.Changes() implementation in the non-aufs
case.

We need to do this because we still support aufs
and users on other drivers can push incompat images
to the registory that aufs users cannot use.

This makes the device mapper tool work again and adds new features
to get pool status, device status and to list all devices.

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.

This is the proposed fix for #2506. It provides a more complete message
with regards to name collisions including informing of the opposing
containers ID.
I have included a test to ensure that the correct short id is displayed
to make the message easier to understand.

Finish container cleanup before setting the state to stopped.
Otherwise, for an application that exits quickly, a call to Restart
can allow Start to be called again before cleanup is done, resulting in
overritten data in the Container struct.

Each arg to docker run should be placed in a separate string.
Otherwise, when starting the command via exec.Cmd, the command is
interpreted as "echo test", which can't be found.
