This repository has no history, making it hard to review

[eternaleye]

This repository seems to be based on P-H-C/phc-winner-argon2 - however, it seems like the code was committed to an entirely new repository, losing the history and making it difficult to review the changes in isolation.

I've taken the liberty of integrating the changes over the commit that they seem to have been developed on top of (P-H-C/phc-winner-argon2@30c78a1) in eternaleye/Argon2-Practical-Graph:preserve-history, followed by rebasing them onto current master in eternaleye/Argon2-Practical-Graph:preserve-history-rebased.

I also changed the commenting-out of the distribution calculation to use #if 0, to minimize the amount of unnecessary churn (such as stripping the /* */ comment directives from comments in that section).

I'd appreciate if you'd review what I did to make sure I haven't made any mistakes, and possibly integrate the incremental form in this repository for ease of comprehension and review.
