This adds more type safety to libgirepository, and allows differentiating the `GIBaseInfo` derived types using the type system. Two new derived types had to be added (previously they were just a collection of helper methods which worked directly on a `GIBaseInfo` and didn’t check types): `GICallbackInfo` and `GIUnresolvedInfo`. Further cleanups and refactoring might be needed on this, but the core of libgirepository now uses `GTypeInstance` and appears to still work (it’s difficult to be entirely sure because there are no unit tests yet).
