    logging: add lswlog_to_error_stream(); rename others to be consistent
    
    The library code can emit output using any of the following "streams":
    
    - logging (can include whack; for pluto LOG_WARNING)
    - error (for pluto LOG_ERR)
    - whack (hopefully pluto only)
    - debug
    
    and lets not forget STDOUT and STDERR.
