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 🎆

Remove do{ } while(0) wrapper around error macros. As pointed out by Faless, a do{ } while(0) wrapper around a continue or break just ends the do{ } while(0) loop. The do{ } while(0) loop exists to enable the macro to be used as a function which requires a semicolon. The alternative approach is to use an if(1) { } else ((void)0) wrapper. Since the macro already has an if(unlikely(m_cond)) { } this patch simply adds the else ((void)0) to this if statement instead. For consistency all the macros have been updated in the same way, and trailing else warnings corrected. However, the wrappers around ERR_PRINT and WARN_PRINT were removed, because they generated too many ambiguous trailing else warnings. They are also single line macros so a wrapper is not needed.

Remove do{ } while(0) wrapper around error macros. As pointed out by Faless, a do{ } while(0) wrapper around a continue or break just ends the do{ } while(0) loop. The do{ } while(0) loop exists to enable the macro to be used as a function which requires a semicolon. The alternative approach is to use an if(1) { } else ((void)0) wrapper. Since the macro already has an if(unlikely(m_cond)) { } this patch simply adds the else ((void)0) to this if statement instead. For consistency all the macros have been updated in the same way, and trailing else warnings corrected. However, the wrappers around ERR_PRINT and WARN_PRINT were removed, because they generated too many ambiguous trailing else warnings. They are also single line macros so a wrapper is not needed.
