* B) If several types of ports are connected, then we should guess based
* on the likeliness of the user wanting to use a given type.
* We assume that the DataTypes are ordered from the most likely to the
* least likely when iterating or comparing them with "<".
* C) If no port is connected, the same logic can be applied with all ports
* instead of connected ones. TODO: Try other ideas, for instance look at
* the last plugin output when |for_input| is false (note: when StrictIO
* the outs of the last plugin should be the same as the outs of the route
* modulo the panner which forwards non-audio anyway).
* All of these constraints are respected by the following algorithm that
