content: initial implementation of content store 
After experimenting with pull, we've defined a transactional content
store for verified storage of fetched items. A base component of
containerkit, this will interact with both the runtime and distribution
sides of the system, avoiding coupling.

Blob access if provided through direct access to readonly files.

c2da97c4d1 containerkit: layer manipulator overlay poc 
A light weight overlay implementation that emits working mounts is
demonstrated. One can prepare and commit changes. The diffs are
correctly held on disk.

The next step from here is to implement the changes methods and ensure
that we can work with the docker registry API.

34b630c861 layers: add design and structure of layer manipulator 
We define the approach and API of the LayerManipulator. It provides a
model for a bare bones graph driver using a simplified snapshotting
model. Callers Prepare and Commit diff paths to build up a tree of
interelated layers, all without being coupled to the layer diff format
or an image runtime.

api: begin to define the containerkit api 
This commit cuts out the structure for defining grpc services for this
project. To provide compatibility with go package generation and support
reuse, we use a single protobuf file per package and make the import
paths relative to the GOPATH.

This first pass attempts to position the Mount type as the lingua franca
of ContainerKit. The Images service will provide paths prepared for use
as a set of mounts of the container service.

We'll need to merge the container service in place with new file defined
here.
