Change types of all PBKDF2 params to `int` as they are `int` in `evp.h`. Check that `raw_keylen` fits into `int` before passing it to OpenSSL. Fix: nodejs#5396

@shigeki I'm afraid that CI is down 😢 (please pardon my terrible sense of humor). |

You can condense the check callback to just /Bad key length/.

LGTM with a suggestion. |
|
@bnoordhuis I took some courage and changed the rest of "Bad key length" occurrences. Hopefully this is OK to you. |

CI is unhappy with the change. Looks like I will need to study this a bit more than I thought. |

You should probably write this as:
if (!std::isfinite(raw_keylen) || raw_keylen < 0 || raw_keylen > INT_MAX) {

CI is green, the commit goes in. Landed in da3f425, thank you everyone! |
