6e022a382d Fix canvas rect bound calculation
It turns out the calculation of the bounding rect for canvas items has a nasty bug. When a transform is applied (especially in a custom draw), in the renderer this extra matrix is applied to all later commands in the canvas item. However in the calculation of the bound, the transform is only applied to the first command following the transform.

This PR fixes this inconsistency.

0dacc681b6 Fixed unnecessary bvh tree updates when calling set_pairable
Dynamic BVH doesn't update the tree anymore when calling set_pairable
with no parameter change.

Also modified Godot Physics broadphase to create objects directly with
pairable (static) set correctly to make use of this optimization for the
BVH broadphase.

Note: Octree broadphase doesn't use this optimization because it forces
an update on move, so passing the proper AABB and static parameters on
creation would cause the tree to update twice.

SCons: Add explicit dependencies on thirdparty code in cloned env
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.

Core: Drop custom copymem/zeromem defines
We've been using standard C library functions `memcpy`/`memset` for these since
2016 with 67f65f6639.

There was still the possibility for third-party platform ports to override the
definitions with a custom header, but this doesn't seem useful anymore.

Backport of #48239.

Fix crash caused by null parameter passed to CameraServer.add_feed()
Fixes #46181

9327052bed [Godot Physics]: Correct typo in moment of inertia calculations.
The moment of inertia calculation for BoxShape is:

```
Vector3(
    (p_mass / 3.0) * (ly * ly + lz * lz), 
    (p_mass / 3.0) * (lx * lx + lz * lz), 
    (p_mass / 3.0) * (lx * lx + ly * ly));
```

where the final line includes both the x and y extents.

However, for CapsuleShape3D, CylinderShape3D, ConvexPolygonShape3D, ConcavePolygonShape3D, and HeightMapShape3D, the final line read `(p_mass / 3.0) * (extents.y * extents.y + extents.y * extents.y)`.  I believe this is a mistake, considering the comment in each case mentions using an AABB approximation, which should follow the same approach as BoxShape.

This change corrects the final line to include both the x and y components of the shape's extent.

- Fix objects with no material being considered as fully transparent by the lightmapper.
- Added "environment_min_light" property: gives artistic control over the shadow color.
- Fixed "Custom Color" environment mode, it was ignored before.
- Added "interior" property to BakedLightmapData: controls whether dynamic capture objects receive environment light or not.
- Automatically update dynamic capture objects when the capture data changes (also works for "energy" which used to require object movement to trigger the update).
- Added "use_in_baked_light" property to GridMap: controls whether the GridMap will be included in BakedLightmap bakes.
- Set "flush zero" and "denormal zero" mode for SSE2 instructions in the Embree raycaster. According to Embree docs it should give a performance improvement.

b1e24597e7 Renaming rendering/2d project settings.
The rendering/quality/2d section of project settings is becoming considerably expanded in 3.2.4, and arguably was not the correct place for settings that were not really to do with quality.

3.2.4 is the last sensible opportunity we will have to move these settings, as the only existing one likely to break compatibility in a small way is `pixel_snap`, and given that the whole snapping area is being overhauled we can draw attention to the fact it has changed in the release notes.

Class reference is also updated and slightly improved.

`pixel_snap` is renamed to `gpu_pixel_snap` in the project settings and code to help differentiate from CPU side transform snapping.

847a37b196 Change 2d transform snapping from floor to round
Two common problems have emerged as a result of transform snapping:
1) Camera jitter with a camera following a snapped object
2) Pixel gaps between e.g. a platform and a player, where a platform rounds down and a player rounds up

Using round seems to greatly reduce problems due to camera jitter. It also may prove better for  pixel gaps because pixel art is often designed on a grid, so whole numbers are too expected, which are unstable with floor().

e7d1735bff GLES - fix some sanitizer warnings
These are benign but worth fixing as it clears the log to find more important errors.

A common problem with the sanitizer is that enums are often used to represent bits (e.g. 1, 2, 4, 8 etc) but without specifying the enum type, the compiler is free to use unsigned or signed int. In this case it uses int, and when it performs bitwise operations on the int type, the sanitizer complains.

This is probably because a bitshift with negative signed value can give undefined behaviour - the sanitizer can't know ahead of time that you are using the enum for sensible bitflags.

4485b43a57 Modernize atomics
- 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

6d89f675b1 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)
