[issue26798] add BLAKE2 to hashlib

[Gregory P. Smith]

Gregory P. Smith added the comment:

CPython should not attempt make a judgement about the safety of a particular function.  We can only document if something has known issues.

We should only include things in the stdlib which are either (a) standard or (b) widely used regardless of being standard.  Given that librsync and RAR both support BLAKE2 and that it is defined by an RFC, I'd say it should go in.

The reference implementation appears to have Apache 2.0 licensed C code would can fall back to when the OpenSSL in use does not include it.

PEP-452 seems to address the necessary API changes.
