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.
