This renames the license file (so automated tooling can find it, which I care
about) and also pulls in some documentation and comment changes, plus some
functional changes:
PR#33 -- future-proof the algorithm field.
PR#34 -- disallow upper case in hex portion.
No changes appear to be required to containerd code.
