When using a prefix or suffix containing an invalid filename character, it's not entirely clear where the errors come from. We make these errors more consistent across platforms. In addition, all permission prompts for tempfile and tempdir were printing the same API name. We also take the opportunity to make the tempfile random space larger by 2x (using a base32-encoded u64 rather than a hex-encoded u32).
