This race condition made me pull my hair. `wl_display_roundtrip` has its
own little event loop, which apparently conflicts hard with the
always-running event loop thread.
I kinda assumed that it would be thread-safe thanks to its internal
`wl_display_prepare_read` call that the docs talk about but that's
clearly not enough.
Luckily this method is called very few times and the only dangerous
instances are in the initialization routine, which first starts the
thread and then does various roundtrips. Libdecor has also some internal
roundtrips of its own which would often fail. Starting the thread after
all initialization fixes the issue.
Tested this by spamming *lots* of `wl_display_roundtrip` in
`WaylandThread::init()` with and without this fix.
* Add a new GodotInstance GDCLASS that provides startup and iteration commands to control a Godot instance.
* Adds a libgodot_create_godot_instance entry point that creates a new Godot instance and returns a GodotInstance object.
* Adds a libgodot_destroy_godot_instance entry point that destroys the Godot instance.

Without this, the screen does go into idle after a few minutes on a RPi5 with default install (wayland w/ labwc), even
though `screen_keep_on` is set. DBUS is enabled but apparently, the screensaver call is not enough.
Previously, libudev was ignored if SOWRAP_ENABLED was defined (it is defined by default) because otherwise it would crash CI builds due to a missing header, and dbus was always linked dynamically. This commit should fix this issue and make libudev usable again
Made possible by EIREXE, xsellier and the SDL team.
This commit includes statically linked SDL3 for Windows, Linux and macOS.
The vendored copy of SDL3 was setup to only build the required subsystems
for gamepad/joystick support, with some patches to be able to make it as
minimal as possible and reduce the impact on binary size and code size.

The `Vector2i` division operator casts doubles down to `int32_t`. It
would thus truncate the fractional scale factor to 0 if less than 1,
resulting in a FPE on x86_64.
