This will make it possible to have mappings for different controllers
that have the same VID/PID. This happens frequently with some generic
controller boards that have been reused in many products.
Fixes https://github.com/libsdl-org/SDL/issues/6004
This prevents crashes when calling SDL joystick API functions from a different thread while disconnection is happening.
See https://github.com/libsdl-org/SDL/issues/6063 for a more thorough review of joystick locking.
* Added support for mini-gamepad mode for Joy-Con controllers, matching the mapping for hid-nintendo on Linux and iOS 16
* Added the ability to merge left and right Joy-Con controllers into a single Pro-style controller
* Added the hint SDL_HINT_JOYSTICK_HIDAPI_SWITCH_COMBINE_JOY_CONS to control this merging functionality
* Removed the hint SDL_HINT_JOYSTICK_HIDAPI_JOY_CONS
The HIDAPI joystick driver doesn't properly reset the change counter
it uses to track if re-enumeration is needed when the joystick
subsystem is quit and then reinitialized.
The first SDL_Init(SDL_INIT_JOYSTICK) will result in the expected
HIDAPI joysticks appearing, but subsequent calls will result in no
joysticks being enumerated until another HIDAPI joystick is added
or removed from the system.
This allows us to handle controllers that use the Xbox protocol but look like Nintendo Switch or Playstation controllers, like the Qanba Dragon Arcade Stick in PC mode
This prevents conflicts with hidapi linked with applications, as well as allowing applications to make use of HIDAPI on Android and other platforms that might not normally have an implementation available.
The Game Controller Kit doesn't show the controllers at startup, so the HIDAPI driver sees them first and therefore gets preference when a controller is supported by both drivers.
This fixes bug https://github.com/libsdl-org/SDL/issues/4209
To enter Bluetooth pairing mode hold B and Action (button with circle) buttons for 3 seconds.
It works via usual HIDAPI if special filter driver is not installed:
https://www.amazon.com/gp/help/customer/display.html?nodeId=GZCT4CTFHXLHEB9T
With that driver installed it mimics Xbox One controller and works via XInput under Windows.
Under DInput this controller is not usable at all.
When Xbox One/Series Controllers are connected via USB on Windows they all are using `XBOXGIP` driver and produce a special ProductID `0x02FF` (GIP software PID) for any connected controller.
On the other hand `Xbox 360 Wireless Controller Reciever` (PID 0x0719) is using `XUSB` driver and produces special ProductID `0x02A1` (XUSB software PID) for each connected Xbox 360 Wireless Controller.
Also fixed Xbox One Series X Controller comment.
I have a buggy system which reports a udev "change" event for an empty
USB-C port every 0.14 seconds, which causes annoying frame hitches
because SDL decides that means it needs to do a libusb hid_enumerate,
which is slow (~25ms!) because of the get_usb_string() calls in there.
We only need to re-enumerate if we've seen a device added or removed, so
let's filter out the change event first.

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.
