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.
- Fix project settings being ignored.
- Made usages of `native_thread_allocator` thread-safe.
- Remove redundant thread-safety from `low_priority_threads_used`, `exit_threads`.
- Fix deadlock due to unintended extra lock of `task_mutex`.
* Node processing works on the concept of process groups.
* A node group can be inherited, run on main thread, or a sub-thread.
* Groups can be ordered.
* Process priority is now present for physics.
This is the first steps towards implementing https://github.com/godotengine/godot-proposals/issues/6424.
No threading or thread guards exist yet in most of the scene code other than Node. That will have to be added later.
Instead of reading files over the network, the new version uses a local file cache and only updates files when it changes.
The original remote filesystem was created 14 years ago, when ethernet was faster than hard drives or even flash. Also, mobile devices have a very small amount of storage.
Nowadays, this is no longer the case so the approach is changed to using a persistent cache in the target device.

On Linux, thread IDs were not properly assigned with the current approach.
The line:
`std::thread new_thread(&Thread::callback, _thread_id_hash(thread.get_id()), p_settings, p_callback, p_user);`
does not work because the thread ID is not assigned until the thread starts.
This PR changes the behavior to use manually generated thread IDs. Additionally, if a thread is (or may have been created) outside Godot, the method `Thread::attach_external_thread` was added.
This allows properly limiting what features depend on the RegEx module
(doing the actual conversion) and what features only require the renames
data (GDScript suggestions).
Also better excludes the conversion command line options when actually
disabling deprecated code.
Fixes#73029.
MangoHud would be shown on every popup in multi-window mode, and seemed
to cause rendering issues for various users.
There are also issues with RTSS, and VkBasalt also doesn't seem
particularly good to use in the editor.
All these stay available to enable when running the project itself,
including running from the editor (so running the editor after e.g.
`export MANGOHUD=1` in the environment will ignore it for the editor,
but use it when playing the project).
Fixes#57403.
Fixes#57937.
* Overrides no longer happen for set/get.
* They must be checked with a new function: `ProjectSettings::get_setting_with_override()`.
* GLOBAL_DEF/GLOBAL_GET updated to use this
This change solves many problems:
* General confusion about getting the actual or overriden setting.
* Feature tags available after settings are loaded were being ignored, they are now considered.
* Hacks required for the Project Settings editor to work.
Fixes#64100. Fixes#64014. Fixes#61908.
`const` is used on all methods, even when they cause modification of the server. This reworks the methods of the server to only use `const` on method that don't change the state of the server.
