Miek Gieben 775cf92f03 plugin/loop: show from -> to (#2400) 
Show from and to address when detecting a loop they may aid in
debugging.

Hard to create a unit test, but this is a startup run with self induced
loop:

~~~ corefile
.:1053 {
    loop
    log
    forward . 127.0.0.1:1053
}
~~~~

Update the docs and polished that a bit as well.
