missing xen packages on ftp

[Maxime Villard <max%m00nbsd.net@localhost>]

I've searched through all of the recent directories in

	http://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/i386/

And there is not a single xentools package. xenkernel is there, sometimes,
but version 4.2, which is outdated and doesn't receive security updates
anymore.

Can we bring them back, please? At a time they were there, and you could
just do pkgin on a fresh install. Why do packages disappear like that?
