tarball methods in preparation for migrating away from the sparse tree layout. This re-introduces 14883:6568c1882af5 and 14862:98efd2e410ae plus further fixes. Also add makefile fragments to support building the paravirt ops tree (make linux-2.6-paravirt-build). Signed-off-by: Ian Campbell <ian.campbell@xensource.com>
