Just don't specify a base class if you want to base your class directly
on GTypeInstance, e.g.

public class MyObject {
...
}

The reason we've changed this is that GTypeInstance is not a real class,
it is just a C helper structure used to implement your own fundamental
class. Fundamental classes don't have a base class and this fact is now
more appropriately represented in Vala.
