Thanks a lot for the PR! Just as a heads-up, I am busy with job interviews for probably at least another month, so it will be a while until I will be able to review this PR. |

This PR allows
libc::opento be called using two or three arguments as defined in https://man7.org/linux/man-pages/man2/open.2.htmlThe presence of the third argument depends on the value of the second argument. If the second argument dictates that the third argument is required miri will emit an error if the argument is missing. If the second argument does not require a third argument, then the argument is ignored and passed as 0 internally (it would be ignored by libc anyway)
