Registers type_id as the predefined identifier and type_name as the
name of a fundamental type. If type_id is already registered, or a
type named type_name is already registered, the behaviour is undefined.
The type system uses the information contained in the GTypeInfo structure
pointed to by info and the GTypeFundamentalInfo structure pointed to by
finfo to manage the type and its instances. The value of flags determines
additional characteristics of the fundamental type.
