Enable inspection (aka "shallow pull") of images' manifest info, and
also the creation of manifest lists (aka "fat manifests").
The workflow for creating a manifest list will be:
`docker manifest create new-list-ref-name image-ref [image-ref...]`
`docker manifest annotate new-list-ref-name image-ref --os linux --arch
arm`
`docker manifest push new-list-ref-name`
The annotate step is optional. Most architectures are fine by default.
There is also a `manifest inspect` command to allow for a "shallow pull"
of an image's manifest: `docker manifest inspect
manifest-or-manifest_list`.
To be more in line with the existing external manifest tool, there is
also a `-v` option for inspect that will show information depending on
what the reference maps to (list or single manifest).

The current implementation of the ElectAuthServer doesn't handle well when the
default Registry server is not included in the response from the daemon Info
endpoint.
That leads to the storage and usage of the credentials for the default registry
(`https://index.docker.io/v1/`) under an empty string on the client config file.
Sample config file after a login via a Docker Daemon without Registry
information:
```json
{
"auths": {
"": {
"auth": "***"
}
}
}
```
That can lead to duplication of the password for the default registry and
authentication failures against the default registry if a pull/push is performed
without first authenticating via the misbehaving daemon.
Also, changes the output of the warning message from stdout to sdterr as
per dnephin suggestion.
