 So feel free to shoot me for suggesting this, but I think it'd be
better to have the default depend on how we got the URLs. If we get a
list from a mirrorlist, then assume priority, but if we get a list of
baseurls then assume roundrobin.
 This is also better backwards compat.

 But if that's too magic, priority everywhere is better than current
behaviour.
