David Benjamin e216d6bb9f Add PKCS8_{decrypt,encrypt}_pbe.
The original functions do an ascii_to_ucs2 transformation on the password.
Deprecate them in favor of making that encoding the caller's problem.
ascii_to_ucs2 doesn't handle, say, UTF-8 anyway. And with the original OpenSSL
function, some ciphers would do the transformation, and some wouldn't making
the text-string/bytes-string confusion even messier.
