The "shortid" syntax was added in d26a3b37a6,
and allowed for matching an image on its ID prefix (this is before images were
content-addressable). With the introduction of content-addressable references,
this syntax became problematic, and Docker deprecated this syntax in 2016
(Docker v1.13.0) through commit; 5fc71599a0
> The `repository:shortid` syntax for referencing images is very little used,
> collides with tag references, and can be confused with digest references.
Support for this syntax was removed in 2017 (Docker 17.12) through commit:
a942c92dd7
containerd uses a fork of the reference package with this syntax removed, and
does not support this syntax:
901bcb2231
This patch removes the deprecated syntax, the ParseAnyReferenceWithSet function,
and the ShortIdentifierRegexp regex.
As there are no external consumers for this function, nor the regexp, I'm
skipping a deprecation cycle for this;
- https://grep.app/search?q=.ShortIdentifierRegexp
- https://grep.app/search?q=.ParseAnyReferenceWithSet%28

Go 1.13 and up enforce import paths to be versioned if a project
contains a go.mod and has released v2 or up.
The current v2.x branches (and releases) do not yet have a go.mod,
and therefore are still allowed to be imported with a non-versioned
import path (go modules add a `+incompatible` annotation in that case).
However, now that this project has a `go.mod` file, incompatible
import paths will not be accepted by go modules, and attempting
to use code from this repository will fail.
This patch uses `v3` for the import-paths (not `v2`), because changing
import paths itself is a breaking change, which means that the
next release should increment the "major" version to comply with
SemVer (as go modules dictate).

ParseDockerRef normalizes the image reference following the docker
convention. This is added mainly for backward compatibility. The reference
returned can only be either tagged or digested. For reference contains both tag
and digest, the function returns digested reference, e.g.
docker.io/library/busybox:latest@sha256:7cc4b5aefd1d0cadf8d97d4350462ba51c694ebca145b08d7d41b41acc8db5aa
will be returned as
docker.io/library/busybox@sha256:7cc4b5aefd1d0cadf8d97d4350462ba51c694ebca145b08d7d41b41acc8db5aa.

The common use case for this function is to add a default tag if the
reference only has a name. The current behavior only adds the default
tag if there is no *tag*, which requires most callers to check for a
digest. Change the behavior to only add default tags to name-only
references, and change the name to reflect this. The documentation
already described the new behavior, so it does not need to be changed.

The NormalizedNamed interface has shown to not be necessary for
integrating the change downstream. The FamiliarName and FamiliarString
helpers are the only used interface and allow hiding the normalized
completely.

Officials repositories always have 2 part names with the first part
being library and second part being the offical repository name. Names
with more than 2 parts should not hit the special case for official
repositories since they are not valid official repositories.
Add tests for this ambiguity and to ensure that 3 part names are
supports for the default repository, as used by the docker store.

NamedRepository only needs to be used internally. Additionally this
interface may go away in the future and be merged with Named.

Add interface for for a normalized name and corresponding parser for that type.
New normalized versions of all interfaces are not added since all type information is preserved on calls to Familiar.
