How do you propose to handle any pokemon that evolve from trading, friendship, or like Glacion that can only evolve in certain places??

There is going to be a professor that will specialize in Pokemon Evolutions. You'll have to visit this professor in order to make these types of Pokemon evolve. This applies to all forms of evolution besides regular leveling up.
