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.
This closes#13649

It should not print to STDOUT so that it only prints the debugTransport
output if there was an error in one of the registry tests.

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.

Thanks to @dmcgowan for noticing.
Added a testcase to make sure Save() can create the dir and then
read from it.

This PR does the following:
- migrated ~/.dockerfg to ~/.docker/config.json. The data is migrated
but the old file remains in case its needed
- moves the auth json in that fie into an "auth" property so we can add new
top-level properties w/o messing with the auth stuff
- adds support for an HttpHeaders property in ~/.docker/config.json
which adds these http headers to all msgs from the cli
In a follow-on PR I'll move the config file process out from under
"registry" since it not specific to that any more. I didn't do it here
because I wanted the diff to be smaller so people can make sure I didn't
break/miss any auth code during my edits.
