- Remove some old debugging printf's

- Formalize the Windoze output
- The facilities for lazy opening of files were already included in
  here (yay foresight!); so just don't open the file aggressively when
  we ompi_output_open(); instead, let the first ompi_output() open the
  file.  This allows the session directory to stay empty (and
  therefore removable) if the file is never written to.

This commit was SVN r3800.
