Most places in the registry were using string types to refer to
repository names. This changes them to use reference.Named, so the type
system can enforce validation of the naming rules.

https://github.com/docker/distribution/pull/1249 changed token fetching
to parse HTTP error response bodies as serialized errcodes. However,
Docker Hub's authentication endpoint does not return error bodies in
this format. To work around this, convert its format into
ErrCodeUnauthorized or ErrCodeUnknown.

Add a generic Manifest interface to represent manifests in the registry and
remove references to schema specific manifests.
Add a ManifestBuilder to construct Manifest objects. Concrete manifest builders
will exist for each manifest type and implementations will contain manifest
specific data used to build a manifest.
Remove Signatures() from Repository interface.
Signatures are relevant only to schema1 manifests. Move access to the signature
store inside the schema1 manifestStore. Add some API tests to verify
signature roundtripping.
schema1
-------
Change the way data is stored in schema1.Manifest to enable Payload() to be used
to return complete Manifest JSON from the HTTP handler without knowledge of the
schema1 protocol.
tags
----
Move tag functionality to a seperate TagService and update ManifestService
to use the new interfaces. Implement a driver based tagService to be backward
compatible with the current tag service.
Add a proxyTagService to enable the registry to get a digest for remote manifests
from a tag.
manifest store
--------------
Remove revision store and move all signing functionality into the signed manifeststore.
manifest registration
---------------------
Add a mechanism to register manifest media types and to allow different manifest
types to be Unmarshalled correctly.
client
------
Add ManifestServiceOptions to client functions to allow tags to be passed into Put and
Get for building correct registry URLs. Change functional arguments to be an interface type
to allow passing data without mutating shared state.

There seems to be a need for a type that represents a way of pointing
to an image, irrespective of the implementation.
This patch defines a Reference interface and provides 3 implementations:
- TagReference: when only a tag is provided
- DigestReference: when a digest (according to the digest package) is
provided, can include optional tag as well
Validation of references are purely syntactic.
There is also a strong type for tags, analogous to digests, as well
as a strong type for Repository from which clients can access the
hostname alone, or the repository name without the hostname, or both
together via the String() method.
For Repository, the files names.go and names_test.go were moved from
the v2 package.

Fixes https://github.com/docker/distribution/issues/1062
This relaxes the naming restrictions places on Docker images to permit
valid hostnames according to [RFC-2396](https://www.ietf.org/rfc/rfc2396.txt).
It deviates from the RFC in the following ways:
1) Allow underscores where we allow hyphens (hostnames don't allow
underscores, which we must for backwards compatibility).
2) Leave "top-level" name segments unrestricted (domains require an
alpha character to begin a top-level domain, e.g. "com").
3) DO NOT allow a trailing dot, as permitted by FQDNs.

This allows the administrator to specify an externally-reachable URL for

To bring ErrorCode into liine with Go conventions, ErrorCode.Error() now
returns the "nice" value of the error code. This ensures error message assembly
works similar to commonly used Go conventions when directly using ErrorCode as
an error.

Some missing descriptions and error code for tags pagination was cleaned up to

This change adds a basic catalog endpoint to the API, which returns a list,
or partial list, of all of the repositories contained in the registry. Calls
to this endpoint are somewhat expensive, as every call requires walking a
large part of the registry.
Instead, to maintain a list of repositories, you would first call the catalog
endpoint to get an initial list, and then use the events API to maintain
any future repositories.

Move the specification to use a Link header, rather than a "next" entry in the
json results. This prevents requiring clients from parsing the request body to
issue the next request. It also ensures that the returned response body does
not change in between requests.
The ordering of the specification has been slightly tweaked, as well. Listing
image tags has been moved after the catalog specification. Tag pagination now
heavily references catalog pagination.

This contains a proposal for a catalog API, provided access to the internal
contents of a registry instance. The API endpoint is prefixed with an
underscore, which is illegal in images names, to prevent collisions with
repositories names. To avoid issues with large result sets, a paginated version
of the API is proposed. We make an addition to the tags API to support
pagination to ensure the specification is conistent.

This changeset provides a common http handler for serving errcodes. This should
unify http responses across webservices in the face of errors.
Several type assertions have been added, as well, to ensure the error interface
is implemented.

The main goal of this changeset is to allow repository name components to
consist of a single character. The number of components allowed and the slash

To go along with this simplification, errant constants and unneeded error types
have been removed.

Per the comment on line 498, this moves the logic of setting the http
status code into the serveJSON func, leaving the auth.Challenge.ServeHTTP()
func to just set the auth challenge header.
