Add a VCS=none that does nothing, use it instead of VCS=svn

Earlier versions of this patch added VCS=xbs, but XBS is
non-functional.  It provided something useful before db-functions-$VCS
was a thing, but now it's dead.

We don't use SVN, and XBS non-functional, just add a null VCS that
does nothing.
