REVISION SUMMARY
  The "_copied" property in basefilectx is used by renamed() and
  copysource(). committablefilectx (which memfilectx subclasses)
  overrides renamed() and writes it in terms of copysource() instead of
  _copied. That means that the nodeid part of "_copied" is memfilectx is
  unused. Let's instead override copysource() too so we don't need the
  "_copied".
