This could be useful debugging functionality, but:

- we have a layout dump feature already, which is available in
  dbglevel<2 (and even non-dbgutil) builds already
- for SAL_DEBUG() these functions would have to work with an STL stream,
  not with an SvStream

So there is little value in keeping these.
