Make project more generic?

[gaul]

I recently saw @PatPennell's libinput-disable-on-click-scrolling project/fork and wonder if this project should grow in scope to allow further configuration. Some symbols like libinput_device_config_middle_emulation_set_enabled and libinput_device_config_scroll_set_button can be looked up at run-time via dlsym but others like LIBINPUT_CONFIG_MIDDLE_EMULATION_ENABLED are enums.

@Nicronics recently created libinput-force-tap-to-click as well.
