[SDL3] Adding input and FFB support for Logitech G29(PS3) on hidapi

[Kethen]

#11591 for SDL3

companion test program for SDL3 https://github.com/Kethen/sdl_lg4ff_util/tree/SDL3_lg4ff

WINE has not moved onto SDL3 so it cannot be tried on WINE at the moment

This is an impressive PR. How does this interact with other drivers, like new-lg4ff? Is there any reason we'd want this active when those are available?

Thanks but a large portion of it was ported from https://github.com/berarma/new-lg4ff

How does this interact with other drivers, like new-lg4ff?

On Linux, it depends on how it was opened:

• If it was opened on /dev/hidraw*, kernel drivers would stay active, and if the wheel is accessed through both drivers, it will be receiving confusing commands from two sources, tho it's generally fine if active effects are on only one side at a time
• If it was opened on /dev/bus/usb/* using libusb, exclusive access should be obtained and kernel drivers will unprobe

Which path would happen depends on which hidapi backend SDL was built to use and device node permissions

On MacOS, if I understand correctly some games also use IOHIDManager to provide wheel support on their own. SDL3 currently does not grab exclusive access

SDL/src/hidapi/SDL_hidapi.c

Line 1246 in 4742922

hid_darwin_set_open_exclusive(0);

No idea if existing games grab exclusive access

On Windows, I have no idea how it would react with the Logitech driver, no idea if any exclusive access would happen when hidapi opens the device from CM_Get_Device_Interface_List fetched interface names

Is there any reason we'd want this active when those are available?

On Linux, evdev does not provide an analog to GetEffectStatus, user is expected to track that as effects are uploaded, I think https://bugzilla.kernel.org/show_bug.cgi?id=219189; otherwise I'd expect the kernel drivers to have better latency profiles

As for availability, unless udev rules were supplied (usb) (hidraw), the evdev backend would be used on SDL

On Windows, once again I have no idea

[Kethen]

Added build fixes for platforms with hidapi disabled, without M_PI, and Android

Still need help with MSVC project files

rebased and fixed windows building

If code was taken from there, is there permission to relicense it from GPL to zlib?
