I guess we could ask the main original Blake author, Jean-Philippe, if he
would mind OpenSSL renaming Blake2b and Blake2s to Blake256 and Blake512.
Jean-Philippe, would you mind?  The names Blake2b and Blake2s are both
confusing and not similar to other names in OpenSSL.  Another alternative
might be Blake2-256 and Blake2-512, but Blake256 and Blake512 will be
simpler for OpenSSL users to grok.  What do you and Zooko think?
