Comment:

 I don't think that's what I meant: I meant that an intro point should be
 able to have an ntor onion key, and also (say) have some other kind of
 onion key for some day in the future, too, in case we add a successor to
 ntor.

 So I think the code in decode_introduction_point needs to handle looking
 for the first `onion-key ntor` line.  Otherwise it will ignore it if the
 ntor one isn't in the first position.

 Also the spec should say something like "At least once per intro point;
 each key type must be unique per intro point"
