On macOS / iOS, to get the IFNAME of a UTUN, a `getsockopt(fd, SYSPROTO_CONTROL, UTUN_OPT_IFNAME, val, len);` call must be made passing not a struct, but a CString of `IFNAMSIZ` bytes, which returns how many bytes of the CString was written to (including with null-terminating byte). This implements getsockopt for bytes.
…O_CONTROL, UTUN_OPT_IFNAME, val, len);`; depends on ref nix-rust#866

This is weird enough that I don't want to merge it without a test. It's ok if the test requires root access. We already have some like that, for example |
