We've added support to the registry command to report the current version of
the distribution package. The version package is generated with a shell script
that gets the latest tag and add "+unknown". This allows builds from "go get"
and "go install" to have a rough version number. Generated periodically, it
will provide a decent indication of what code built the binary. For more
accurate versioning, one can build with the "binaries" make target. Linker
flags are used to replace the version string with the actual current tag at
build time.

Also removed ModTime checks on directories as it is not
required and some drivers might fail to provide it.

This change provides a toolkit for intercepting registry calls, such as
`ManifestService.Get` and `LayerUpload.Finish`, with the goal of easily
supporting interesting callbacks and listeners. The package proxies
returned objects through the decorate function before creation, allowing one to
carefully choose injection points.
Use cases range from notification systems all the way to cache integration.
While such a tool isn't strictly necessary, it reduces the amount of code
required to accomplish such tasks, deferring the tricky aspects to the
decorator package.

This speeds up the build (and makes it more consistent) since it doesn't have to clone a bunch of repos. 👍

Setting a header for all responses can help clients better determine
if the server speaks the legacy v1 API or the v2 API. It is important
that the header be set *BEFORE* routing the request.

In support of making the storage API ready for supporting notifications and
mirroring, we've begun the process of paring down the storage model. The
process started by creating a central Registry interface. From there, the
common name argument on the LayerService and ManifestService was factored into
a Repository interface. The rest of the changes directly follow from this.
An interface wishlist was added, suggesting a direction to take the registry
package that should support the distribution project's future goals. As these
objects move out of the storage package and we implement a Registry backed by
the http client, these design choices will start getting validation.
