7925670f81 Add frame delta smoothing option (4.x)
Frame deltas are currently measured by querying the OS timer each frame. This is subject to random error. Frame delta smoothing instead filters the delta read from the OS by replacing it with the refresh rate delta wherever possible.

This PR also contains code to estimate the refresh rate based on the input deltas, without reading the refresh rate from the host OS.

The delta_smooth_enabled setting can also be modified at runtime through OS::, and there is also now a command line setting to override the project setting.

One Copyright Update to rule them all
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.

It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).

We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).

Also fixed "cf." Frenchism - it's meant as "refer to / see".

6be702bace Fix negative delta arguments
Three attack points, all after the regular calculations:
1. Prevent negative physics timestep counts. They could occur if
   physics_jtter_fix is changed at runtime.
2. idle_step is not allowed to go below 1/8th of the input step.
   That could happen on physics_jitter_fix changes or heavily
   fluctuating performance.
3. Prevent that the idle_step modification breaks the promise
   that Engine.get_physics_interpolation_fraction() is between
   0 and 1 by doing more physics steps than the base system wants.

Rename iterations_per_second to physics_ticks_per_second
This makes it clearer that this property is only about physics FPS,
not rendering FPS.

The `physics_fps` project setting was also renamed to
`physics_ticks_per_second` for consistency.

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 🎆

1f6f364a56 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.

Happy new year to the wonderful Godot community!

We're starting a new decade with a well-established, non-profit, free
and open source game engine, and tons of further improvements in the
pipeline from hundreds of contributors.

Godot will keep getting better, and we're looking forward to all the
games that the community will keep developing and releasing with it.

bf6c301b9c Add access to interpolation fraction for fixed timestep interpolation
Addresses 

This is a prerequisite for allowing proper support for fixed timestep interpolation, exposing the interpolation fraction to the engine, modules and gdscript.

The interpolation fraction is the fraction through the current physics tick at the time of the current frame.
