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 🎆

Core: Move DirAccess and FileAccess to `core/io` File handling APIs are typically considered part of I/O, and we did have most `FileAccess` implementations in `core/io` already.

#include "core/io/file_access.h"
Make core/ includes absolute, remove subfolders from include path This allows more consistency in the manner we include core headers, where previously there would be a mix of absolute, relative and include path-dependent includes.

Modernize Thread - Based on C++11's `thread` and `thread_local` - No more need to allocate-deallocate or check for null - No pointer anymore, just a member variable - Platform-specific implementations no longer needed (except for the few cases of non-portable functions) - Simpler for `NO_THREADS` - Thread ids are now the same across platforms (main is 1; others follow)

Port member initialization from constructor to declaration (C++11) Using `clang-tidy`'s `modernize-use-default-member-init` check and manual review of the changes, and some extra manual changes that `clang-tidy` failed to do. Also went manually through all of `core` to find occurrences that `clang-tidy` couldn't handle, especially all initializations done in a constructor without using initializer lists.

Fix warnings on non-static data member initializers (C++11 feature) We're not formally using C++11 yet so those trigger compilation warnings (at least with GCC 5): ./main/input_default.h:122:30: warning: non-static data member initializers only available with -std=c++11 or -std=gnu++11 CursorShape default_shape = CURSOR_ARROW; ^ Note: We may allow those eventually (especially for non-int static const), but most of current occurrences were inconsistent with all other classes.

Fix of AudioRecordingEffect property For debug purposes the boolean whether the recording is active or not were an editor property. It has been removed to avoid users leaving it on true on close, causing it to be saved in the default_bus_layout It was also renamed to better describe its functionality related to issue: 20487
