The current Dev version of TarSum includes hashing of extended file attributes and omits inclusion of modified time headers. I refactored the logic around the version differences to make it more clear that the difference between versions is in how tar headers are selected and ordered. TarSum Version 1 is now declared with the new Dev version continuing to track it. Docker-DCO-1.1-Signed-off-by: Josh Hawn <josh.hawn@docker.com> (github: jlhawn)
