Registers @type_name as the name of a new dynamic type derived from @parent_type. The type system uses the information contained in the #GTypePlugin structure pointed to by @plugin to manage the type and its instances (if not abstract). The value of @flags determines the nature (e.g. abstract or not) of the type.
