hvmloader: relicense hvmloader xenbus implementation under more liberal terms.

This code is a great example of a simple xenbus implementation and we would
like to reuse it in projects with non-GPLv2 license (specifically in this case
SeaBIOS which is GPLv3).

I picked the license from extras/mini-os/COPYING (A two clause BSD style
license) since mini-os exists for much the same purpose.

This change has been Acked in principal by Tim and Keir (who are the only
people to have touched this file). But I would like to have their Acks of the
specific change before committing.
