Unlike Mutter and Sway, KWin actually checks the serial passed in
wl_pointer_set_cursor(). The serial provided is supposed to be the
serial of the pointer enter event, but We were always passing 0.
This caused KWin to drop our requests to hide the cursor.
Thanks to the KDE folks for spotting this in my debug logs.
Fixes#3576
In the extremely unlikely event that inotify is not available (and,
therefore, HAVE_INOTIFY is not #defined), SDL will no-longer build.
This is because <unistd.h> is only included when HAVE_INOTIFY is
defined, and PR #4098 adds a call to access(…, F_OK), which requires
<unistd.h>.
(Note that the F_OK symbol is the only one which actually prevented
SDL from compiling, but both access() and close() fell back to implicit
definitions, which is a bit concerning.)
Fixes: 8d43f45a7b ("Don't use udev for joystick enumeration if running in a container")
If we are running in a container, like Flatpak[1] or pressure-vessel[2],
it's likely that we are using user namespaces,
therefore udev event notification via netlink won't work reliably.
Use their filesystem API to detect them and automatically fallback to
the inotify-based enumeration.

This improves SDL's ability to detect HIDAPI joystick hotplug in a
container environment because we cannot reliably receive events from
udev in a container.
For a more detailed explanation of why this issue happens with
containers, please check the previous commit
"joystick: Use inotify to detect joystick unplug if not using udev"
(b0eba1c5).

As already explained in the previous commit "joystick: Allow libudev to
be disabled at runtime" (13e7d1a9), libudev can fail in a container.
To make it easier to experiment with, we add a new environment variable
"SDL_HIDAPI_JOYSTICK_DISABLE_UDEV" that disables udev and let it
fallback to the device enumeration using polling.

This fixes problems with controllers not being re-detected when a computer goes to sleep and a controller is removed and plugged back in while it's asleep.
Renamed COPYING.txt to LICENSE.txt, and ensured the copyright year
is the first line in the license file. This causes GitHub to correctly
identify the zlib license and report it on SDL's project page.
Fixes SDL_CreateWindowAndRenderer (and similar situations) not choosing a Metal backend. See #3991.
Passing an explicit backend into CreateWindow, eg SDL_WINDOW_OPENGL or SDL_WINDOW_METAL, will still prevent the window from being used with other backend types.
