When requesting a token, the basic auth header is always being set even
if there is no username value. This patch corrects this and does not set
the basic auth header if the username is empty.
Also fixes an issue where pulling all tags from a v2 registry succeeds
when the image does not actually exist on the registry.

Under certain cases, such as when putting a manifest or check for the existence
of a layer, the status code checks in session_v2.go were too narrow for their
purpose. In the case of putting a manifest, the handler only cares that an
error is not returned. Whether it is a 304 or 202 does not matter, as long as
the server reports success. Having the client only accept specific http codes
inhibits future protocol evolution.

While the v2 pull operation is writing the body of the layer blob to disk
it now computes the tarsum checksum of the archive before extracting it to
the backend storage driver. If the checksum does not match that from the
image manifest an error is raised.
Also adds more debug logging to the pull operation and fixes existing test
cases which were failing. Adds a reverse lookup constructor to the tarsum
package so that you can get a tarsum object using a checksum label.

Add support for pulling signed images from a version 2 registry.
Only official images within the library namespace will be pull from the
new registry and check the build signature.
