We were calling Stat for each layer to get the size so we could indicate
progress, but https://github.com/docker/distribution/pull/1226 made it
possible to get the length from the GET request that Open initiates.
Saving one round-trip per layer should make pull operations slightly
faster and more robust.

This change allows API clients to retrieve an authentication token from
a registry, and then pass that token directly to the API.
Example usage:
REPO_USER=dhiltgen
read -s PASSWORD
REPO=privateorg/repo
AUTH_URL=https://auth.docker.io/token
TOKEN=$(curl -s -u "${REPO_USER}:${PASSWORD}" "${AUTH_URL}?scope=repository:${REPO}:pull&service=registry.docker.io" |
jq -r ".token")
HEADER=$(echo "{\"registrytoken\":\"${TOKEN}\"}"|base64 -w 0 )
curl -s -D - -H "X-Registry-Auth: ${HEADER}" -X POST "http://localhost:2376/images/create?fromImage=${REPO}"

Currently, the resources associated with the io.Reader returned by
TarStream are only freed when it is read until EOF. This means that
partial uploads or exports (for example, in the case of a full disk or
severed connection) can leak a goroutine and open file. This commit
changes TarStream to return an io.ReadCloser. Resources are freed when
Close is called.
