Beyond adding default zero-initialization, this commit changes undefined initialization to zero, as some cases reserved the padding and on other cases, I've found some systems act strange when giving uninit instead of zero even when it shouldn't be an issue, one example being FileProtocol.Open's attributes, which *should* be ignored when not creating a file, but ended up giving an unrelated error.
