Modified Files:
        src/sys/fs/union: union.h union_subr.c

Log Message:
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.
