device: combine debug and info log levels into 'verbose'
...
There are very few cases, if any, in which a user only wants one of
these levels, so combine it into a single level.
While we're at it, reduce indirection on the loggers by using an empty
function rather than a nil function pointer. It's not like we have
retpolines anyway, and we were always calling through a function with a
branch prior, so this seems like a net gain.

device: change logging interface to use functions
...
This commit overhauls wireguard-go's logging.
The primary, motivating change is to use a function instead
of a *log.Logger as the basic unit of logging.
Using functions provides a lot more flexibility for
people to bring their own logging system.
It also introduces logging helper methods on Device.
These reduce line noise at the call site.
They also allow for log functions to be nil;
when nil, instead of generating a log line and throwing it away,
we don't bother generating it at all.
This spares allocation and pointless work.
This is a breaking change, although the fix required
of clients is fairly straightforward.

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")
}
