With the switchover to the unified reference package, AddReference no
longer does the right thing when passed a reference that has both a
digest and a tag. It would put both the digest in the tag in the
reference stored in the repositories.json file, which isn't the right
format, and would mean that neither "docker run" nor docker services
could locate the image. This meant that a simple "docker service create"
command like "docker service create --name foo busybox top" would create
a service that immediately went into a restart loop, because it couldn't
use the image that had been pulled.
Fix AddReference to strip out the tag when both a tag and digest are
specified. We do this because we don't necessarily want to overwrite the
tag - when both a digest and tag are specified, the tag is only
advisory.

Remove forked reference package. Use normalized named values
everywhere and familiar functions to convert back to familiar
strings for UX and storage compatibility.
Enforce that the source repository in the distribution metadata
is always a normalized string, ignore invalid values which are not.
Update distribution tests to use normalized values.

Use resolving to repo info as the split point between the
legitimate reference package and forked reference package.

The `digest` data type, used throughout docker for image verification
and identity, has been broken out into `opencontainers/go-digest`. This
PR updates the dependencies and moves uses over to the new type.

This PR makes restores the pre-Docker 1.10 behavior of allowing
uppercase characters in registry hostnames.
Note that this only applies to hostnames, not remote image names.
Previous versions also prohibited uppercase letters after the hostname,
but Docker 1.10 extended this to the hostname itself.
- Vendor updated docker/distribution.
- Add a check to "normalize" that rejects remote names with uppercase
letters.
- Add test cases to TestTagValidPrefixedRepo and
TestTagInvalidUnprefixedRepo
Fixes: #20056
