GDScript: Refactor builtin functions They are now called "utility functions" to avoid confusion with methods of builtin types, and be consistent with the naming in Variant. Core utility functions are now available in GDScript. The ones missing in core are added specifically to GDScript as helpers for convenience. Some functions were remove when there are better ways to do, reducing redundancy and cleaning up the global scope.

Update copyright statements to 2021 Happy new year to the wonderful Godot community! 2020 has been a tough year for most of us personally, but a good year for Godot development nonetheless with a huge amount of work done towards Godot 4.0 and great improvements backported to the long-lived 3.2 branch. We've had close to 400 contributors to engine code this year, authoring near 7,000 commit! (And that's only for the `master` branch and for the engine code, there's a lot more when counting docs, demos and other first-party repos.) Here's to a great year 2021 for all Godot users 🎆

GDScript: Refactor builtin functions They are now called "utility functions" to avoid confusion with methods of builtin types, and be consistent with the naming in Variant. Core utility functions are now available in GDScript. The ones missing in core are added specifically to GDScript as helpers for convenience. Some functions were remove when there are better ways to do, reducing redundancy and cleaning up the global scope.
