Patch to scan /dev/dri based on names rather than file type
Loading KMS/DRM on FreeBSD fails because the "available" code in the driver checks for character device nodes under /dev/dri and the /dev/dri/card* files are symlinks rather than device nodes nodes on FreeBSD. The symlink points to /dev/drm/0.
The attached patch counts /dev/dri/card* entries rather than directory entries which are character devices.

I think what happening with the software renderer is:
* you're somehow in background (so texture creation is not possible)
* it resizes and wants to push a SDL_WINDOWEVENT_SIZE_CHANGED
It call:
https://hg.libsdl.org/SDL/file/a010811d40dd/src/render/SDL_render.c#l683
* GetOutputSize
* SW_GetOutputSize
* SW_ActivateRenderer
* SDL_GetWindowSurface
* SDL_CreateWindowFramebuffer which is mapped to SDL_CreateWindowTexture
and it ends up re-creating the surface/a texture, while being in background

There is an issue on the latest commit of the mercurial repo when SDL_THREADS_DISABLED is set:
src/core/linux/SDL_threadprio.c:79:28: error: unknown type name 'Sint64'; did you mean 'int'
It was originally added to work around an input event problem in the code of a specific app which mixed SDL and native UIViews, but that app solved its problems in a better manner since then.
Also implemented SDL_JoystickGetDevicePlayerIndex() on iOS and tvOS, and added support for reading the new menu button state available in iOS and tvOS 13.
(technically, this function never returns an error at this point, but since
it _does_ have an "uhoh, is this corrupt data?" comment that it ignores, we
should probably make sure we handle error cases in the future. :) )

Pressing a trigger button on a Steam Controller causes a segmentation fault both with stable version and latest mercurial head on Linux. I'm using the recent hid_steam kernel module with lizard_mode disabled (that is no keyboard/mouse emulation). I suspect this is what's happening: the driver exposes two hats. The two hats have indices 0 and 2. Inside linux/SDL_sysjoystick.c two hats are allocated in allocate_hatdata for joystick->hwdata->hats. In HandleHat function the hat parameter (that can be 2) is directly used as the index of the array that only has two elements, causing an out of bounds access. SDL is not expecting to have "holes" between hats indices.
The index 2 is calculated in HandleInputEvents() as (ABS_HAT2X - ABS_HAT0X) / 2 where ABS_HAT2X is the value associated to the hat inside the hid_steam module.

The attached patch adds support for single-touch evdev devices.
These devices report ABS_X, ABS_Y and BTN_TOUCH events. This patch sets them up as MT devices with a single slot and handles the appropriate messages.
