[Xcb] xinput.xml: remaining misc patches

[Christian Linhart]

Hi,

In the next five posts, I'll post the remaining patches.

These are of different, misc categories.

This is the last set of patches from my xinput-review.

P.S.: With these patches, we hopefully have a stable base
for the next tasks.
Which are:
* implementing the features in the generator
  which are necessary for full xinput support.
* modifying xinput.xml accordingly to support the full protocol
  in a way that's also suitable for byte-order conversion
  as e.g. needed for server-side xcb.

I plan to finish complete xinput support by the end of this week.
I'll post patches for individual TODO-items 
as soon as I'll have finished and tested them
(together with the testcases).
