A previous inspection of the code surrounding zero-length blobs led to
some interesting question. After inspection, it was found that the hash
was indeed for the empty string (""), and not an empty tar, so the code
was correct. The variable naming and comments have been updated
accordingly.

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 registry uses partial Named values which the named parsers
no longer support. To allow the registry service to continue
to operate without canonicalization, switch to use WithName.
In the future, the registry should start using fully canonical
values on the backend and WithName should no longer support
creating partial values.

The identifier fields were using spaces while the rest
of the lines were using tabs!

Add details for release checklist for where to put the update
the changelist and which branch to cherry-pick from. Also add
more details around creating the tag and verifying the tag is
correct.

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.

When get manifest, the handler will try to retrieve it from storage driver. When storage driver is cloud storage, it can fail due to various reasons even if the manifest exists
(like 500, 503, etc. from storage server). Currently manifest handler blindly return 404 which can be confusing to user.
This change will return 404 if the manifest blob doesn't exist, and return 500 UnknownError for all other errors (consistent with the behavior of other handlers).

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.

Once upon a time, we referred to manifests and images interchangably.
That simple past is no more. As we grow, we update our nomenclature and
so follows our code.
