Use rustix instead of calling libc directly, which factors out several unsafe blocks and simplifies error handling. There is still one `unsafe` block needed, to dereference raw file descriptors passed in from the user, since the crate still uses `AsRawFd`. Once I/O safety is stablized in std, this crate can switch to using `AsFd`, which will eliminate the last `unsafe` block. This splits out just the API-compatible parts of yoshuawuyts#14. It does not include the changes to use the `AsFd` trait in the public API, so it's not an API-breaking change.
