Fix 3D moving platform logic Same thing that was already done in 2D, applies moving platform motion by using a call to move_and_collide that excludes the platform itself, instead of making it part of the body motion. Helps with handling walls and slopes correctly when the character walks on the moving platform. Also made some minor adjustments to the 2D version and documentation.

Bullet physics engine implementation This is a bullet wrapper that allows Godot to use Bullet physics and benefit about all features. Also it support all specific Godot physics functionality like multi shape body, areas, RayShape, etc.. It improve the Joints, Trimesh shape, and add support to soft body even if Godot is not yet ready to it.

struct RecoverResult {
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.

Style: Remove inconsistently used `@author` docstrings Each file in Godot has had multiple contributors who co-authored it over the years, and the information of who was the original person to create that file is not very relevant, especially when used so inconsistently. `git blame` is a much better way to know who initially authored or later modified a given chunk of code, and most IDEs now have good integration to show this information.
