curl_ntlm_core.c:150: warning 'Curl_des_set_odd_parity' undefined; assuming extern returning int
... so improve the #ifdefs for using our local implementation.
SSLeay was the name of the library that was subsequently turned into OpenSSL many moons ago (1999). curl does not work with the old SSLeay library since years. This is now reflected by only using USE_OPENSSL in code that depends on OpenSSL.
Added Curl_des_set_odd_parity() for use when cryptography engines don't include this functionality.
