* PR162
        * net/if_ppp.c ppp_txdaemon(), net/if_pppvar.h pppstart(): Local
	variables must not be used in a device write routines.  Now
	ppp_softc structure have own character for writing to device
	(sc_outchar).  I think that converting local variables to static
	is not a right solution, because problems will occur in the case
	of two or more ppp instances.
	* net/ppp_tty.c pppstart(): Type of the ioffset variable must be
	u_long, otherwise in the case of the big output packet endless
	loop may occur.
