Same as the corresponding ei change a few commits ago, this one does all the EIS renaming in the same manner. As with the libei changes, an EIS implementation must now handle the EIS_DEVICE_CAP_BUTTON and EI_DEVICE_CAP_SCROLL capabilities. In virtually all cases, clients will likely expect that a device with the pointer or absolute pointer capabilities will also have button and scroll capabilities.
