Title: Extended RC config to 18 channels, dealing with multi-port messages

This increases the max. number of channels to 18 (its currently in the PX4 config section, but I'd be happy to generalize if other autopilots show some interest).

It also teaches the general code sections how to deal with the port field of some messages.
