Implement more tty flags for better portability from other systems:

	XCASE - canonical input/output processing
	IUCLC - translate uppercase to lowercase on input
	OLCUC - translate lowercase to uppercase on output
	OCRNL - translate carriage return to newline on output
	ONOCR - do not output carriage return at column 0
	ONLRET - newline performs carriage return function

In addition the tty compatibility interface supports LCASE properly.

Look at termios(4) for a more complete description of the above flags.
