bouyer-xen2 merged in current

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hi,
I just merged the bouyer-xen2 branch to current. This means that it will
be in 3.0.
I also have changes to integrate Xen in the i386 build (so that xen kernels
are part of the i386 release), including a xen-install kernel which allows to
run sysinst in a non-privileged xen domain. I'll post the diff shortly.
