The current status is stored in the SDL_rwops 'status' field to be able to determine whether a 0 return value is caused by end of file, an error, or a non-blocking source not being ready.
The functions to read sized datatypes now return SDL_bool so you can detect read errors.

This involved moving an `#ifdef` out of SDL_audio.c for thread priority,
so the default ThreadInit now does the usual stuff for non-Android platforms,
the Android platforms provide an implementatin of ThreadInit with their
side of the `#ifdef` and other platforms that implement ThreadInit
incorporated the appropriate code...which is why WASAPI is touched in here.
The Android bits compile, but have not been tested, and there was some
reworkings in the Java bits, so this might need some further fixes still.
This does an enormous amount of work in SDL_immdevice.c to simplify and
clean up that interface, while moving some of its responsibilities to the
higher level SDL_audio.c. I hope I saw the whole picture here, and this
wasn't foolhardy of me.
WASAPI has not been updated for these changes, or for SDL3 at all, yet. As
such, it continues to be broken for now. It will be updated soon.
This code compiles with my cross compiler, but hasn't been built with
Visual Studio, or tested in any form, so there might be obvious fixes
following along shortly.
This call is actually a left-over when porting from fcitx4 service to the new org.freedesktop.portal.Fcitx supported by both fcitx4/fcitx5. CloseIC is actually never a part of the new interface on org.freedesktop.portal.Fcitx. It cause any issue user visible effect.
On 32-bit platforms such as i386, if SDL is compiled with -D_TIME_BITS=64
to opt-in to ABIs that will not stop working in 2038, the fields in
this struct change their naming and interpretation.
The Linux header <linux/input.h> defines macros input_event_sec and
input_event_usec which resolve to the right struct field to look at.
The actual field names and types are an implementation detail,
historically signed 32-bit time.tv_sec and time.tv_usec on 32-bit
platforms, but becoming unsigned __sec and __usec when using 64-bit
time (which makes them able to represent times up to 2106).

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.

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.

In newer kernels, devices that can be positively identified as a
particular device type (for example accelerometers) get a property
bit set. Plumb this information through into the function, but don't
use it for anything just yet.

udev distinguishes between ID_INPUT_KEY, a device with any keyboard keys
at all (including for example USB numeric keypads, Bluetooth headsets
with volume control buttons, and some game controllers; and
ID_INPUT_KEYBOARD, a reasonably fully-featured keyboard that you could
use for general-purpose text entry. If we do the same here, then it's
useful input to our heuristics for identifying devices: for example,
a device with ID_INPUT_KEY could reasonably be a gamepad, but a device
with ID_INPUT_KEYBOARD certainly isn't.

Consolidate the X11_WMCLASS and WAYLAND_WMCLASS envvars into one SDL_HINT_APP_ID hint. This hint serves the same purpose on both windowing systems to allow desktop compositors to identify and group windows together, as well as associate applications with their desktop settings and icons.
The common code for retrieving the value is now consolidated under core/unix/SDL_appid.c as it's common to *nix platforms, and the value is now retrieved at window creation time instead of being cached by the video driver at startup so that changes to the hint after video initialization and before window creation will be seen, as well as to accommodate cases where applications want to use different values for different windows.
They can vanish for UP TO EIGHT SECONDS...!
This is for devices that connect to HDMI/DisplayPort/etc, where it
presumably has to wait for a display to get up and running before it
can play audio through it, so one can see the audio device fail when
changing display modes, or the system returning from sleep. Since this
can be triggered by a game changing video resolutions at startup (either
before or after opening the audio device!), it's important to deal with.
In normal conditions, it shouldn't take this long to open or recover an
audio device, but this is better than unexpectedly losing the device
in this situation.

(cherry picked from commit 48e71ae87b)
If the text-scaling-factor setting is available via D-Bus, add a listener and update the content scale values for the displays if the value is changed during runtime.
Factors out the D-Bus message pump from the system theme detection code to the general D-Bus code, as it's now used for more purposes than just the system theme.
