This allows the application to tell when a joystick polling cycle is complete and can process state changes as a single atomic update. It is disabled by default, at least for now.
It is possible for retrieving the machine ID to fail, either because
dbus was installed incorrectly (machine ID absent or corrupt), or in
32-bit builds, because stat() on the machine ID fails with EOVERFLOW
if it has an out-of-range timestamp or inode number.
dbus has historically treated this as a faulty installation, raising
a warning which by default causes the process to crash. Unfortunately,
dbus_get_local_machine_id() never had a way to report errors, so it has
no alternative for that (bad) error handling.
In dbus >= 1.12.0, we can use dbus_try_get_local_machine_id() to get
the same information, but with the ability to cope gracefully with
errors. ibus won't work in this situation, but that's better than
crashing.

This makes it so you can interact with sensors on multiple threads, as long as only one thread initializes and cleans up the sensor subsystem.
This also has the benefit that sensor data is available as soon as possible.
The hidraw device may take additional time to get the correct permissions for us to open it. In my tests on Steam Deck hardware, this ranges between 5-8ms.
To match the focus stealing prevention logic from windows/osx.
I didn't implement SDL_HINT_WINDOW_ACTIVATE_WHEN_SHOWN as there is no
standard mechanism for us to do so. In most cases marking a window as OverrideRedirect
will cause to not acquire focus when mapped. And in steam we are doing that when
appropriate.
I still left a note in X11_ShowWindow() regarding this behaviour.
- Cocoa_ShowWindow will order a window that is not being activated below the key window (if one exists) then set visible
- Cocoa_RaiseWindow calls -[NSWindow orderFront:] without changing the key window
Also renamed SDL_GetDisplayOrientation() SDL_GetDisplayCurrentOrientation()
The natural orientation of the primary display is the frame of reference for accelerometer and gyro sensor readings.
If a device is positively identified as an accelerometer, pointing stick
or clickpad, then we don't need to second-guess it.
In practice this does not change the result for any device in our
test data, so add some artificial records that exercise this.
