We now use doubles until the last minute, which makes it so we can move
the pointer more precisely. This also includes a fix for tablet tools,
which move absolutely and sometimes do not update the X or Y axis.
- 'libinput' (backend's) to libinput_context
- 'device' (libinput_device) to libinput_dev
- 'dev' (wlr_device) to wlr_dev
- 'devices' lists tangling of libinput devices to wlr_devices
- 'devices' list of wlr_devices in backend state to wlr_device_lists
