Because the repository name definitions are part of the v2 specification, they
have been moved out of the common package. This is part of the effort to break
up the common package into more sensible components.

This changeset provides data structures and definitions describing the routes
available in the V2 registry API. These route descriptors are structured to
provide automated registration, for creating routers, in addition to complete
documentation duty. It's also a possibility that this could be used to
enumerate test coverage for server implementation.
Using this functionality, we've also developed a template to automatically
generate and API specification for submission into docker core.
This changeset integrates the AccessController into the main registry app. This
includes support for configuration and a test implementation, called "silly"
auth. Auth is only enabled if the configuration is present but takes measure to
ensure that configuration errors don't allow the appserver to start with open
access.
URL values may be required to complete an upload in a single POST request,
which may include digest and size. This is not implemented in the server side,
yet, but is part of the HTTP API specification.
Routes and errors are now all referenced from a single v2 package. This
packages exports are acceptable for use in the server side as well as
integration into docker core.
To provide a single package with v2 API definitions, the locked down portions
of the API have been merged into a single package. References to exported items
will appear as v2.XXX, indicating their origin. The definitions in this package
will soon be locked down for change, acceppting only additions that will not
change protocol behavior.
The URLBuilder is now exported with documentation for its behavior. Its a light
wrapper around gorilla mux that avoids one having to remember exact arguments
take by each route.
To lock down V2 api routing, we are moving it to a separate package, with an
exported router creation function and route names. Updates will follow to
prepare the package for export.
To support accurate specification generation, this changeset includes a quick
and dirty tool to generate a markdown table of error codes generated by the
registry API. Equivalent supports for routes will likely follow.
Exported descriptors could be used to generate other documentation, as well.
This commit locks down the set of http error codes that will be part of the
inital V2 specification, proposed in docker/docker#9015. The naming order has
been slightly changed and there are few tweaks to ensure all conditions are
captured but this will be set the docker core will be impleemnted against.
To support this, the errors have been moved into an api/errors package. A new
type, ErrorDescriptor, has been defined to centralize the code, message and
definitions used with each type. The information therein can be used to
generate documentation and response code mappings (yet to come...).
In addition to the refactoring that came along with this change, several tests
have been added to ensure serialization round trips are reliable. This allows
better support for using these error types on the client and server side. This
is coupled with some tweaks in the client code to fix issues with error
reporting.
Other fixes in the client include moving client-specific errors out of the base
package and ensuring that we have correct parameters for finishing uploads.
