Looks up or registers a type that is implemented with a particular
type plugin. If a type with name type_name was previously registered,
the GType identifier for the type is returned, otherwise the type
is newly registered, and the resulting GType identifier returned.
When reregistering a type (typically because a module is unloaded
then reloaded, and reinitialized), module and parent_type must
be the same as they were previously.
As long as any instances of the type exist, the type plugin will
not be unloaded.
Since 2.56 if module is NULL this will call g_type_register_static()
instead. This can be used when making a static build of the module.
