virtualx-engine/modules/dlscript/godot.h
Karroffel 6c49fe9c62 [DLScript] added variant constructor and a function to get userdata of a script 
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.
