f8c09b6a7d Add a new reference package abstracting repositories, tags and digests
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.

776a4ffbe8 Change some incorrect error types in proxy stores from API errors to
distribution errors.  Fill in missing checks for mutations on a registry pull-through
cache.  Add unit tests and update documentation.

Also, give v2.ErrorCodeUnsupported an HTTP status code, previously it was
defaulting to 500, now its 405 Method Not Allowed.

f141480d98 Move common error codes to errcode package
Several error codes are generally useful but tied to the v2 specification
definitions. This change moves these error code definitions into the common
package for use by the health package, which is not tied to the v2 API.

88831b0523 Clean up pagination specification
Some missing descriptions and error code for tags pagination was cleaned up to
ensure clarity. Specifically, we ensure the request variations are named and
the proper error codes are included.

006214d902 Paginate catalog and tag results with Link header
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.

aebe850f73 Catalog V2 API specification proposal
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.

2cf40ab790 Modify blob upload API
- Ensures new uploads and resumed upload statuses always return an offset of 0. This allows future clients which support resumable upload to not attempt resumable upload on this version which does not support it.
- Add PATCH support for streaming data on upload.
- Add messaging to specification that PATCH with content range is currently not supported.
- Update PUT blob to only support full data or no data, no more last chunk messaging as it was not supported.

closes #470

1944be9db3 Stronger validation for uuid field in urls
This change adds strong validation for the uuid variable for v2 routes. This is
a minor specification change but is okay since the uuid field is controlled by
the server. The character set is restricted to avoid path traversal, allowing
for alphanumeric values and urlsafe base64 encoding.

This change has no effect on client implementations.

f536633ca8 spec: fetch manifests by tag or digest
Manifests are now fetched by a field called "reference", which may be a tag or
a digest. When using digests to reference a manifest, the data is immutable.
The routes and specification have been updated to allow this.

There are a few caveats to this approach:

1. It may be problematic to rely on data format to differentiate between a tag
   and a digest. Currently, they are disjoint but there may modifications on
   either side that break this guarantee.
2. The caching characteristics of returned content are very different for
   digest versus tag-based references. Digest urls can be cached forever while tag
   urls cannot.

Both of these are minimal caveats that we can live with in the future.

996235dc59 Specify and implement Docker-Upload-UUID
This changeset adds support for a header to identify docker upload uuids. This
id can be used as a key to manage local state for resumable uploads. The goal
is remove the necessity for a client to parse the url to get an upload uuid.
The restrictions for clients to use the location header are still strongly in
place.
