Currently canonical name gets set to the local name and displayed in the errors.
Canonical name should be the unique and canonical name for an image.
Use docker.io as the canonical domain for images on the public registry.

The docker/distribution dependency was updated in the previous commit to allow
repository name components to only consist of a single letter. The unit tests
have been updated to cement this change.

By adding this header AuthTransport will add Basic authentication to the request and allow 'docker search' results to include private images.

The registry client's TLS configuration used the
default cipher list, including RC4. This change
copies the default cipher list from Golang 1.4 and
removes RC4 from that list. RC4 ciphers are considered
weak and vulnerable to a number of attacks.
Uses the tlsconfig package to define allowed ciphers.

Today, endpoints implementing v2 cannot properly fallback to v1 because the underlying transport that deals with authentication (Basic / Token) doesn't get annotated.
This doesn't affect DockerHub because the DockerHub endpoint appears as 'https://index.docker.io/v1/' (in .dockercfg), and the 'v1' tricks this logic just long enough that the transport is always annotated for DockerHub accesses.

This patch ensures no auth headers are set for v1 registries if there
was a 302 redirect.
This also ensures v2 does not use authTransport.

Refactoring in Docker 1.7 changed the behavior to add this header where as Docker <= 1.6 wouldn't emit this Header on a HTTP 302 redirect.

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.
