[gpm] Resend of patches to add osd for keyboard backlight

[Alex Murray <murray alex gmail com>]

Resending of patches sent previously but this time sending as attachments.

The first patch adds on-screen-display of keyboard brightness level
(which is basically copied and pasted from that in gpm-brightness).
The second patch then gets rid of this duplicated code and unifies it
out into a separate file - gpm-osd-dialog.[ch]

Cheers,
Alex
