Closing a device file takes 0.01 to 0.5s, which can add up to
significant startup delays. The udev classification does not
require opening the actual device files, so, use it if possible,
and only fall back to opening the device and probing otherwise.
LINUX_JoystickInit does a manual scan first so devices are sorted.
If SDL_UDEV_Init hasn't run by then, then the product info cannot
be looked up by SDL_UDEV_GetProductInfo and the initial-plugged-
in-device classification falls back to heuristic guessing.
This fixes getting a deflected axis as the first buffered input reading on a generic USB controller (G-Shark GS-GP702)

using the blocking sceCtrlReadBufferPositive() effectively turns SDL_PollEvent() into WaitForVblank(), because the functions does exactly that if no input is buffered.
due to this, calling SDL_PollEvent() once per frame averaged in 7 ms delay out of the available 16ms budget to get a frame calculated and drawn to achieve 60 fps.
The CRC is used to distinguish between different controllers that have the same VID/PID, so if the CRC doesn't match, it's probably a different controller that we don't know about.

(cherry picked from commit 30e93b40c2)
This broke support for the Hori Fighting Stick EX2, which gets a good mapping if the automatic mapping is allowed to create one.
If the original controller needs a mapping, it should be added with a crc, since that VID/PID combination is used by several HORI controllers.

On Android, HIDAPI prompts for permissions and acquires exclusive access to the device, and on Apple mobile platforms it doesn't do anything except for handling Bluetooth Steam Controllers.

In particular this affects the doomsday game engine if no joystick or
gamepad is attached.

[smcv: Also included minor adjustment from https://github.com/libsdl-org/SDL/pull/9233]
This uses the same chipset as the DragonRise Inc. Generic USB Joystick, which many manufacturers use for different products with different mappings.
In order to add a mapping for a controller using this chipset, we need a unique crc for the device 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.
Fixes https://github.com/libsdl-org/SDL/issues/9031
(cherry picked from commit b7c61569f8)
Add missing guards around use of physicalInputProfile.
Add explicit import of Foundation which seems to be needed on some
systems to get the NSArray definition.
Add __unsafe_unretained to ObjC types in struct so the compiler doesn't
complain about that not being allowed with ARC.
Closes: #8979
(cherry picked from commit e0158f68e4)
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.
Added support for getting the real controller info, as well as the function SDL_GameControllerGetSteamHandle() to get the Steam Input API handle, from the virtual gamepads provided by Steam.
Also added an event SDL_CONTROLLERSTEAMHANDLEUPDATED which is triggered when a controller's API handle changes, e.g. the controllers were reassigned slots in the Steam UI.
