Carve out all libxenlight related sources and move them to tools/libs/light in order to use the generic library build environment. The closely related sources for libxl-save-helper and the libxl test environment are being moved, too. Signed-off-by: Juergen Gross <jgross@suse.com> Acked-by: Wei Liu <wl@xen.org>
