Title: TarSum: versioning

This introduces Versions for TarSum checksums.

Fixes: https://github.com/docker/docker/issues/7526

It preserves current functionality and abstracts the interface for future flexibility. As a POC, the Version1 Tarsum does not include the mtime in the checksum calculation, and would solve https://github.com/docker/docker/issues/7387
