I believe there was a O(n^2) device walking issues on startup
- MaybeAddDevice gets called for every device at startup
- MaybeAddDevice calls IsJoystick
- IsJoystick calls SDL_UDEV_GetProductInfo
- SDL_UDEV_GetProductInfo calls udev_enumerate_scan_devices
- udev_enumerate_scan_devices walks all the devices
Prior to commit 3b1e0e1 this was mostly masked as IsJoystick only
called SDL_UDEV_GetProductInfo when a JSIOCGNAME ioctl was
successful. This fixes the O(n^2) behaviour by directly getting
the device via udev_device_new_from_devnum (based on type, major,
and minor number) instead of enumerating everything via
udev_enumerate_scan_devices and matching on name.

mingw-w64 has added this from Proton (which added this from SDL), so we need to re-define it as a local symbol to avoid conflicting with mingw-w64 headers.

The udev container issue is mostly to do with device notifications
and netlink. The device classification stuff just pokes file in /sys
and /run/udev. Doesn't hurt to try it first for classifying joysticks
and then fall to the guess heuristics if it fails.
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.
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.

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.

Another regression from commit dca3fd8307,
which was a backport of commit de3909a190
from SDL3 to SDL2. This time the regression is much less apparent,
however, due to two reasons:
- It only appears when the SDL project is ran on an actual device
due to magic stringage.
- More importantly, the regression was partially hidden due to
the nature of de3909a190.
The commit which was backported added a single `I` to the JNI method
signature in `SDL_android.c`, representing the added `int axis_mask`
parameter. The parameter was added to both SDL2 and SDL3.
However, notably, that `I` was added *after* commit
fcafe40948, which removed the
`int nballs` parameter from the joystick API, but only from the SDL3
branch.
Therefore, in totality, what should really have been a merge conflict,
was obscured by the fact that the SDL3 branch ended up having
a net-identical JNI signature to the SDL2 branch, due to having
one bool param removed and one added - while, in fact, the SDL2 branch
needed one bool param added and none removed.
keymap can change over time, caching the keymap causes wrong keys
returned when user changes keymap during runtime
