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.

To ensure manifest integrity when pulling by digest, this changeset ensures
that not only the remote digest provided by the registry is verified but also
that the digest provided on the command line is checked, as well. If this check
fails, the pull is cancelled as with an error. Inspection also should that
while layers were being verified against their digests, the error was being
treated as tech preview image signing verification error. This, in fact, is not
a tech preview and opens up the docker daemon to man in the middle attacks that
can be avoided with the v2 registry protocol.
As a matter of cleanliness, the digest package from the distribution project
has been updated to latest version. There were some recent improvements in the
digest package.

The v2 registry will act as a pull-through cache, and needs to be
handled differently by the client to the v1 registry mirror.
See docker/distribution#459 for details
Configuration
Only one v2 registry can be configured as a mirror. Acceptable configurations
in this chanage are: 0...n v1 mirrors or 1 v2 mirror. A mixture of v1 and v2
mirrors is considered an error.
Pull
If a v2 mirror is configured, all pulls are redirected to that mirror. The
mirror will serve the content locally or attempt a pull from the upstream mirror,
cache it locally, and then serve to the client.
Push
If an image is tagged to a mirror, it will be pushed to the mirror and be
stored locally there. Otherwise, images are pushed to the hub. This is
unchanged behavior.

This patch removes the need for requestFactories and decorators
by implementing http.RoundTripper transports instead.
It refactors some challenging-to-read code.
NewSession now takes an *http.Client that can already have a
custom Transport, it will add its own auth transport by wrapping
it.
The idea is that callers of http.Client should not bother
setting custom headers for every handler but instead it should
be transparent to the callers of a same context.
This patch is needed for future refactorings of registry,
namely refactoring of the v1 client code.

Prior to this patch, the response of

- GET /containers/json
- GET /images/(name)/history
display the Created Time as UNIX format which doesn't make sense.
These should be more readable as CLI command `docker inspect` shows.
Due to the case that an older client with a newer version daemon, we
need the version check for now.

As reported in #11294, the Docker daemon will execute contains it
shouldn't run in the event that a requested tag is present in an image's
ID. This leads to the wrong image being started up silently.
This change reduces the risk of such a collision by using the short ID
iff the actual revOrTag looks like a short ID (not that it necessarily
is).

Manifest is now generated during a v2 push, not relying on previously generated hashes. When pushing a layer, the hash is directly calculated from the tar contents which will be pushed. Computing the hash on push ensures that the hash contents always match what is seen by the registry. This also mitigates issues with tarsum differences and permits using pure SHA digests.
Additionally the new manifest function is moved to the unit tests since it is no longer called outside the tests.

manifest code calls TarLayer() and gets archive. This archive needs to
be closed once caller is done using it to release the resrouces held
by archive. For the devicemapper graphdriver, archive keeps a device
mounted (device which is backing the layer). If archive.Close() is not
called, that device remains mounted and later deletion of device fails
leading to various other issues.

The trust graph currently pulls the keys needed to verify official images. For non-official images this graph check is useless. To avoid hitting the key statement url when pulling from private v2 registries, restrict the check to official image pulls.

Pushing by image ID is not allowed in the Docker CLI and not supported by the registry. An unnamed image also cannot be pushed to a private registry, since no endpoint is specified and it will default to the hub. The hub also does not support this use case, therefore removing the code path is the best solution.
The ability to push a layer without a name is unsupported by the v2 registry.

Only show the verification message if all the tarsum checks pass and the image manifest is verified.
No longer return an error when a tarsum verification fails, just reset the verification flag.
Tarsum verification is less meaningful without a verified manifest and therefore it should not cause an error.
Updated the verified image test to pull an image which expected to have a verified manifest and contents.
