Export image/container metadata stored in graph driver. Right now 3 fields
DeviceId, DeviceSize and DeviceName are being exported from devicemapper.
Other graph drivers can export fields as they see fit.
This data can be used to mount the thin device outside of docker and tools
can look into image/container and do some kind of inspection.

Move graph related functions in image to graph package.
Consolidating graph functionality is the first step in refactoring graph into an image store model.
Subsequent refactors will involve breaking up graph into multiple types with a strongly defined interface.

The checksum is now being stored in a separate file beside the image
JSON file.

When we use the engine/env object we can run into a situation where
a string is passed in as the value but later on when we json serialize
the name/value pairs, because the string is made up of just numbers
it appears as an integer and not a string - meaning no quotes. This
can cause parsing issues for clients.
I tried to find all spots where we call env.Set() and the type of the
name being set might end up having a value that could look like an int
(like author). In those cases I switched it to use env.SetJson() instead
because that will wrap it in quotes.
One interesting thing to note about the testcase that I modified is that
the escaped quotes should have been there all along and we were incorrectly
letting it thru. If you look at the metadata stored for that resource you
can see the quotes were escaped and we lost them during the serialization
steps because of the env.Set() stuff. The use of env is probably not the
best way to do all of this.

Now, newly created/imported layers will have the checksum of
the layer diff computed and stored in the image json file.
For now, it is not an error if the computed checksum does not
match an existing checksum, only a warning message is logged. The
eventual goal is to use the checksums in the image JSON to verify
the integrity of the layer contents when doing `docker load` or
`docker pull`, and error out if it does not match.

The argument specified the json data to save to disk when registering
a new image into the image graph. If it is nil, then the given image
is serialized to json and that is written by default. This default
behavior is sufficient if the given image was originally deserialzed
from this jsonData to begin with which has always been the case.

This is a first step towards moving all code related to local
manipulation of images into a cleanly separated subsystem,
accessible via a stable set of commands in the engine API.
`graph.TagStore` now implements `engine.Installer`. For now, it
is installed by `Server.InitServer`, along with all other Server
commands. However this will change in future patches.
`graph.TagStore.Install` registers the following commands:
* `image_set` creates a new image and stores it locally.
* `image_get` returns information about an image stored locally.
* `image_tag` assigns a new name and tag to an existing image.
These commands are a pre-requisite for moving 'push' and 'pull'
out of `Server`.
