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.

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.

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.
