Introduce a new OpenSSL::KDF module as a namespace for to-be-added KDFs. This makes it easier to add new KDFs in future. We already have a stand-alone KDF, OpenSSL::PKCS5.pbkdf2_hmac. This is migrated to the new namespace. The backwards compatibility is retained by the method defined in the newly added lib/openssl/pkcs5.rb.
As a wrapper of NUM2ULONG() or NUM2ULL(). Converts a Ruby object to uint64_t, raising an exception if the conversion fails.
Add OpenSSL::KDF.scrypt as a wrapper around EVP_PBE_scrypt(). This is added by OpenSSL 1.1.0.
