Log message:
	* fhandler_termios.cc (fhandler_termios::bg_check): Do not return EIO when a
	process group has no leader as this is allowed and does not imply an orphaned
	process group.  Add a test for orphaned process groups.
	(tty_min::is_orphaned_process_group): Define new function.
	* tty.h (tty_min::is_orphaned_process_group): Define new function.
