To make the definition of supported digests more clear, we have refactored the
digest package to have a special Algorithm type. This represents the digest's
prefix and we associated various supported hash implementations through
function calls.

The change relies on a refactor of the upstream resumable sha256/sha512 package
that opts to register implementations with the standard library. This allows
the resumable support to be detected where it matters, avoiding unnecessary and
complex code. It also ensures that consumers of the digest package don't need
to depend on the forked sha implementations.
We also get an optimization with this change. If the size of data written to a
digester is the same as the file size, we check to see if the digest has been
verified. This works if the blob is written and committed in a single request.

Vendored resumable sha256/sha512 library. Digest package new exports a
resumable variant of the Digester.

Some dependencies in a PR from an older branch broke the master build. The
change adds the missing dependencies and updates some others.

This dependency added a method to access the current standard logger. This is
required to properly configure the logger for context awareness. The plan is to
have all loggers descend from the standard logger.

There don't seem to be any major changes but we'll update this while we're at
it. This dependency is pretty important for coming changes.

The auth package has been updated to use "golang.org/x/net/context" for
passing information between the application and the auth backend.
AccessControllers should now set a "auth.user" context value to a AuthUser
struct containing a single "Name" field for now with possible, optional, values
in the future.
The "silly" auth backend always sets the name to "silly", while the "token" auth
backend will set the name to match the "subject" claim of the JWT.

As we get closer to release, we need to ensure that builds are repeatable.
Godep provides a workable solution to managing dependencies in Go to support
this requirement. This commit should be bolstered by updates to documentation
and build configuration.
