Xi: return BadImplementation for deviceids 256 and above
The protocol allows for 16 bit device ids, but the implementation doesn't
yet. We need to break the input ABI once more to shift the DeviceIntRec's
CARD8 to a CARD16, along with some changes in the privates.
Once that is done, revert this patch.
