Make union_newlower() ans union_newupper() local to union_subr.c,
expand and remove union_updatevp() and take care to transfer the
vnode lock from the union vnode to its new upper vnode without
breaking the fstrans state.
Add assertions that un_lowervp and un_uppervp never change from
non-NULL to non-NULL.
