Fixes#43733: "creating SpatialMaterial in a separate thread creates invalid
shaders (temporarily)."
The bug occurred because various setters called in materials' constructors add
materials to queues that are processed on the main thread. This means that
when the materials are created in another thread, they can be processed on the
main thread before the constructor has finished.
The fix adds a flag to affected materials that prevents them from being added
to the queue until their constructors have finished initialising all the
members.

They could cause a segfault when parsing values with ID "Resource"
as apparently we never set a valid `func` for it.
Fixes crash part of #42115.

This prevents setting too large values and crashing the editor.
Very low values are also no longer allowed since they are generally
not detailed enough to represent complex gradients, leading to confusion.

A value of 0 rings is valid and results in a non-subdivided cylinder.
Compared to the previous lowest allowed value (1), a value of 0 halves
the triangle count in any cylinder.

Regression fix: update_exports is tool only and should be used only in
the editor, otherwise it can cause export variable overrides from
instances to be discarded in favor of the parent's value.

Since we clone the environments to build thirdparty code, we don't get an
explicit dependency on the build objects produced by that environment.
So when we update thirdparty code, Godot code using it is not necessarily
rebuilt (I think it is for changed headers, but not for changed .c/.cpp files),
which can lead to an invalid compilation output (linking old Godot .o files
with a newer, potentially ABI breaking version of thirdparty code).
This was only seen as really problematic with bullet updates (leading to
crashes when rebuilding Godot after a bullet update without cleaning .o files),
but it's safer to fix it everywhere, even if it's a LOT of hacky boilerplate.

* Better handling of the scene's environment energy in the lightmapper
bakes.
* Fixed a bug where ProceduralSky::get_panorama() returned a reference
instead of a copy.
* Removed includes to Embree's internal header files.

The problem happened when `ImageTexture::create_from_image` was called
with an empty image. In this situation an RID was allocated despite the
texture being null. The destructor would then crash trying to acess this
null texture.

This makes them easier to distinguish, especially when used
in a TileMap.
The default color's opacity has been slightly decreased to account
for the new outline.
- Based on C++11's `atomic`
- Reworked `SafeRefCount` (based on the rewrite by @hpvb)
- Replaced free atomic functions by the new `SafeNumeric<T>`
- Replaced wrong cases of `volatile` by the new `SafeFlag`
- Platform-specific implementations no longer needed
Co-authored-by: Hein-Pieter van Braam-Stewart <hp@tmm.cx>
- 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)
- Based on C++11's `mutex`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed
- Simpler for `NO_THREADS`
- `BinaryMutex` added for special cases as the non-recursive version
- `MutexLock` now takes a reference. At this point the cases of null `Mutex`es are rare. If you ever need that, just don't use `MutexLock`.
- `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same.
- Based on C++14's `shared_time_mutex`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed
- Simpler for `NO_THREADS`
This commit adds a view-dependant fade to the 3D viewport grid. It fades out
at steep view angles to hide the solid regions that appear far from the camera.
I also included a fade to hide the grid borders.
I added some improvements to the dynamic grid when the camera is in orthogonal mode.
It properly handles zoom now, and the grid center is now set to the intersection point
between the grid plane and the camera forward ray, keeping the grid
always visible.
