Joystick Interposer Fixes for SDL, wine, Retroarch and RPCS3

[danisla]

Changes

• Fixes joystick interposer compatibility with Retroarch, wine, and RPCS3.
• Intercepts calls to open64 and makes socket non-blocking when added to an epoll.
• Implements support for interposing /dev/input/event* joystick devices.
• The SDL_JOYSTICK_DEVICE workaround for SDL apps is no longer needed.

Application Specific

Retroarch

To use with retroarch, edit your retroarch.cfg (at ~/.config/retroarch/retroarch.cfg) and set:

input_joypad_driver = "linuxraw"

RPCS3

Select SDL as controller handler then select Selkies Controller 1 from the device list.

Wine

Run wine control and then open the Game Controllers app to test joystick support.

Current work in progress:

• Attempt to interpose evdev to support SDL.

@ehfd I temporarily remove the Conga build steps because they were failing, can you help resolve the errors? You can run the conga docker build locally and see the same failures.

That is in order for the near future. I know the source of error.

Ok maybe we’ll just leave it disabled for now and you can re-enable it the build steps later.

Anyways, when you are ready, press "Ready for review" and I'll directly make necessary edits.
