cleanups and warning fixes

[Jamey Sharp]

These patches fix a bunch of GCC warnings, most of them in dmx. I still
haven't got my tree warning-clean, but this helps a lot.

The patches are mostly pretty independent; feel free to review whatever
strikes your fancy.

The following changes since commit c2d0b3b437b7ce6ce975f2ead4d8bb8295ef0ddc:
  Peter Hutterer (1):
        xfree86: store the InputAttributes in the input device.
