added aix-ssha* pbkdf2 hashes
added 125 byte password self tests (max size). Removed old oSSL commented out code. Fixed issue where a SHA256 constant was used instead of a SHA512.  Should have caused no crashes, since the 512 constant is smaller, but waste of memory
Use code from pbkdf2_hmac_sha512.h.  2x speedup for oSSE, and gets about 4x+ speedup for SSE2 (XOP gets more)
