* add xf86 input driver. * cleanup. * rewrite to unix socket PoC. * add input rebuild. * lint & docs. * add input driver struct. * comments, lint, socket name from config. * add touch events to webrtc. * switch to uint32. * misc update logging & linting, * fix screen size * set touchscreen as core pointer. * add touch to ws control. * SendCoreEvents. * extract to own xinput folder. * add debounce. * switch pressure to uint8. * check buffer size. * send touch events with system init.
