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: Fix mishandling of stack pointers - Replace the for loop temporaries by locals. They cause conflicts with the stack when being popped, while locals are properly handled in the scope. - Change the interface for the codegen so the for loop list doesn't live through the whole block if it's a temporary. - Keep track of the actual amount of local variables in the stack. Using the size of the map is misleading in cases where multiple locals have the same name (which is allowed when there's no shadowing). - Added a few debug checks for temporaries, to avoid them being wrongly manipulated in the future. They should not live more than a line of code. - Rearrange some of compiler code to make sure the temporaries don't live across blocks.

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.

GDScript: Fix mishandling of stack pointers - Replace the for loop temporaries by locals. They cause conflicts with the stack when being popped, while locals are properly handled in the scope. - Change the interface for the codegen so the for loop list doesn't live through the whole block if it's a temporary. - Keep track of the actual amount of local variables in the stack. Using the size of the map is misleading in cases where multiple locals have the same name (which is allowed when there's no shadowing). - Added a few debug checks for temporaries, to avoid them being wrongly manipulated in the future. They should not live more than a line of code. - Rearrange some of compiler code to make sure the temporaries don't live across blocks.
