Log:
  db_script_exec: use a saved script name when reporting commands executed
  
  Before executing a command in a ddb script ddb prints an information
  line of the form:
    db:1:my-script> command
  where 1 is the script's depth level, "my-script" is the scipt's name,
  and "command" is the current command in the script.
  db_script_exec() uses its 'scriptname' parameter to produce that string.
  In the case when db_script_exec() is called from db_run_cmd() the
  argument points to db_tok_string that is a global variable used for
  command parsing.  So, its value changes with every command executed.
  
  This commit changes the code to use the script's name stored in
  ds_scriptname to print the line.
