* Nice Update of PPPD support which eliminates the
	requiremetn that drivers be in the termios TASK_DRIVEN mode.
	Mike did significant testing and reports that it seems to be
	more stable and handle larger packets better.  This patch
	replaces the termios tasks with more general pppd network
	driver tasks.  The functions pppinput() and pppstart() get
	called from the interrupt service routine.
	* libc/termios.c: Added PPCDISC.
