[issue35784] document that hashlib.new takes kwargs

[Christian Heimes]

Christian Heimes  added the comment:

Thanks for the bug report.

While you are technically correct, I would like to hold off on this change for 
a bit more. I plan to replace our internal vendored copies of sha3 and blake2 
with OpenSSL code. OpenSSL 1.1.1 has some of the new required APIs. OpenSSL 
3.0.0-dev is currently adding more but with slightly different semantic. For 
example OpenSSL does not have blake2b, but blake2b512 for hashing and 
blake2bmac for keyed hashing with salting and personalization.

I like to get integration with OpenSSL right until hashlib.new() is officially 
documented.

[issue35784] document that hashlib.new takes kwargs

[Jörn Heissler]

New submission from Jörn Heissler :

This code works:
hashlib.new('blake2b', b'foo', digest_size=7)

https://github.com/python/cpython/blob/master/Lib/hashlib.py#L7
documents the function as: new(name, data=b'', **kwargs)

But the **kwargs argument is missing in 
https://docs.python.org/3/library/hashlib.html#hashlib.new and there aren't any 
examples either.
