bpo-40791: Use CRYPTO_memcmp() for compare_digest by tiran · Pull Request #20456 · python/cpython

@tiran 

:func:`hashlib.compare_digest` uses OpenSSL's ``CRYPTO_memcmp()`` function
when OpenSSL is available.

Note: The ``_operator`` module is a builtin module. I don't want to add
libcrypto dependency to libpython. Therefore I duplicated the wrapper
function and added a copy to ``_hashopenssl.c``.
