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.

The way Repositories() was initially called was somewhat different than
other parts of the client bindings because there was no way to instantiate a
Namespace. This change implements a NewRegistry() function which changes
it so that Repositories() can be called the way one would expect.
It doesn't implement any of the other functions of Namespaces.

This change removes the Catalog Service and replaces it with a more
simplistic Repositories() method for obtaining a catalog of all
repositories. The Repositories method takes a pre-allocated slice
and fills it up to the size of the slice and returns the amount
filled. The catalog is returned lexicographically and will start
being filled from the last entry passed to Repositories(). If there
are no more entries to fill, io.EOF will be returned.

Conflicts:
registry/client/repository.go
registry/handlers/api_test.go
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.

Since the actual port is 5003, it would make sense to name it local-5003 instead of local-8082

After consideration, we've changed the main descriptor field name to for number
of bytes to "size" to match convention. While this may be a subjective
argument, commonly we refer to files by their "size" rather than their
"length". This will match other conventions, like `(FileInfo).Size()` and
methods on `io.SizeReaderAt`. Under more broad analysis, this argument doesn't
necessarily hold up. If anything, "size" is shorter than "length".

An error level log is already produced within app.authorized() if an
actual unexpected error occurs during authorization, so this warning
level log remains for auditability purposes, but should not be
considered an error condition.

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.

Add a functional argument to pass a digest to (ManifestService).GetByTag().
If the digest matches an empty manifest and nil error are returned.
See 1bc740b0d5 for server implementation.
