adding /dev/xen/gnttab

[Christoph Egger <Christoph_Egger%gmx.de@localhost>]

Hi!

For gnttab support a new device file is needed for a new set of ioctl()'s.
Attached patch adds /dev/xen/gnttab.
I would like to use the opportunity to move xen device files
into /dev/xen/. The patch keeps the existing ones for backward
compatibility.

Comments?

Christoph
