tun: use IoctlCtlInfo from golang.org/x/sys/unix on macOS
...
Direct syscalls using unix.Syscall(unix.SYS_*, ...) are discouraged on
macOS and might not be supported in future versions. Switch to use
unix.IoctlCtlInfo to get the kernel control info.

tun: use GetsockoptString in (*NativeTun).Name on macOS
...
Direct syscalls using unix.Syscall(unix.SYS_*, ...) are discouraged on
macOS and might not be supported in future versions. Instead, use the
existing unix.GetsockoptString wrapper to get the interface name.

Previously it was possible for this to race. It turns out we really
don't need to set anything to -1 anyway.

tun: use netpoll instead of rwcancel

The new sysconn function of Go 1.12 makes this possible:
package main
import "log"
import "os"
import "unsafe"
import "time"
import "syscall"
import "sync"
import "golang.org/x/sys/unix"
func main() {
fd, err := os.OpenFile("/dev/net/tun", os.O_RDWR, 0)
if err != nil {
log.Fatal(err)
}
var ifr [unix.IFNAMSIZ + 64]byte
copy(ifr[:], []byte("cheese"))
*(*uint16)(unsafe.Pointer(&ifr[unix.IFNAMSIZ])) = unix.IFF_TUN
var errno syscall.Errno
s, _ := fd.SyscallConn()
s.Control(func(fd uintptr) {
_, _, errno = unix.Syscall(
unix.SYS_IOCTL,
fd,
uintptr(unix.TUNSETIFF),
uintptr(unsafe.Pointer(&ifr[0])),
)
})
if errno != 0 {
log.Fatal(errno)
}
b := [4]byte{}
wait := sync.WaitGroup{}
wait.Add(1)
go func() {
_, err := fd.Read(b[:])
log.Print("Read errored: ", err)
wait.Done()
}()
time.Sleep(time.Second)
log.Print("Closing")
err = fd.Close()
if err != nil {
log.Print("Close errored: " , err)
}
wait.Wait()
log.Print("Exiting")
}

Doing so tends to make the tunnel blocking, so we only retrieve it once
before we call SetNonblock, and then cache the result.
