With no feedback on v5 beyond the need for a .gitignore in the second commit of this v6, I think this series should now be good to go. These are some improvements to the Poly1305 code that I think should be fairly uncontroversial. The first part, the new C implementations, adds cleaner code in two forms that can easily be compared and reviewed, and also results in performance speedups. The second part, the new x86_64 implementation, replaces an slow unvetted implementation with an extremely fast implementation that has received many eyeballs. Finally, we fix up some deadcode.
