Make get.docker.io install directions slightly better by telling user exactly how to add themselves to the "docker" group

As a bonus, if the user has run this script the way we recommend (ie, without "sudo" or "su", run as their user), we can actually give them the exact command they'll need with their correct username substituted appropriately.

Separate out graphdriver mount and container root

This separates out the directory as returned from the graphdriver (the
"base" fs) from the root filesystem of the live container. This is
necessary as the "diff" operation needs access to the base filesystem
without all the mounts that the running container needs (/.dockerinit,
volumes, etc).

We change container in the following way:

Container.RootfsPath() returns the the directory which will be used as
the root in a running container. It is always of the form
"/var/lib/docker/container/<id>/root" and is a private bind mount to
the base filesystem. It is only available while the container is running.

Container.BasefsPath() returns the raw directory from the graph driver
without the container runtime mounts. It is availible whenever the
container is mounted (in between a container.Mount()/Unmount() pair,
which are properly refcounted).

This fixes issue #3840
