From: Oleksandr Andrushchenko <oleksandr_andrushche...@epam.com>
This is the sync up with the canonical definition of the keyboard
protocol in Xen:
1. Add missing string constants for {feature|request}-raw-pointer
to align with the rest of the interface file.
2. Add new XenStore feature fields, so it is possible to individually
control set of exposed virtual devices for each guest OS:
- set feature-disable-keyboard to 1 if no keyboard device needs
to be created
- set feature-disable-pointer to 1 if no pointer device needs
to be created
