Completely re-write the lightmap generation code:
- Follow the general lightmapper code structure from 4.0.
- Use proper path tracing to compute the global illumination.
- Use atlassing to merge all lightmaps into a single texture (done by @RandomShaper)
- Use OpenImageDenoiser to improve the generated lightmaps.
- Take into account alpha transparency in material textures.
- Allow baking environment lighting.
- Add bicubic lightmap filtering.
There is some minor compatibility breakage in some properties and methods
in BakedLightmap, but lightmaps generated in previous engine versions
should work fine out of the box.
The scene importer has been changed to generate `.unwrap_cache` files
next to the imported scene files. These files *SHOULD* be added to any
version control system as they guarantee there won't be differences when
re-importing the scene from other OSes or engine versions.
This work started as a Google Summer of Code project; Was later funded by IMVU for a good amount of progress;
Was then finished and polished by me on my free time.

This change does two things:
1. Properly update the internal shape data using _update_in_shape_owner
when updating a shape (in 2D it was resetting one way collision)
2. Avoid unnecessary updates when calling set_shape with the same shape,
which happens each time a shape property is modified
(e.g shape.extents.x = ...)
Fixes#45090
(cherry picked from commit 4b43cd17c5)
The description for audio_track_set_key_stream referenced a parameter called offset, which is not a parameter for that method. The description now references the correct parameter, stream.

nanosleep returns 0 or -1 not the error code.
The error code "EINTR" (if encountered) is placed in errno, in which case nanosleep can be safely recalled with the remaining time.
This is required, so that nanosleep continues if the calling thread is interrupted by a signal.
See manpage nanosleep(2) for additional details.

Also include public domain assets in `COPYRIGHT.txt` with Unlicence text or
dual-licensing scheme.
And document commit hashes for most thirdparty code in `thirdparty/README.md`
for clarity, and in case there's no tag matching the included version numbers.

The previous RGBA format included unused RGB data. Using the LA8 format
removes the need to store the extra data.
The Docs have been updated to reflect the format changes.

fix for issue #44282
AABB for collision geometry was being calculated based on parent nodes transform without consideration for collision geometries translation.
Also hopefully clarified logic for selecting starting point for ray cast

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 🎆
