The godot_dlinstance_get_userdata() function can be used to get the DLScript userdata pointer of any object that has a DLScript attached to it.
This is particularly useful and even required for language bindings to work properly.
This also fixes non-tool builds.
This module was written by bojidar-bg and me, with the help of ClikCode and touilleMan.
This adds a module to Godot that enables the use of dynamic libraries as a source for scripts.
That also allows third party libraries to be linked to Godot more easily and without creating modules.
