>Description:
	I poposed this enhancement in tech-userlevel and received no
	negative feedback. (Nor positive, for that matter). So, here it
	is.

	This enhancement adds an optional class= parameter to /etc/ttys
	and teaches getttyXXX() parse it. Like the user class in
	master.passwd, it is currently only a hook for local
	functionality (in my case, a log-out-idle-users daemon).
	In the future, it will probably be used as part of the
	login access control system aluded to in ttyaction(3).
	(ie, instead of listing which terminals a user may log in on,
	list the class or classes of terminals)

	This should be 100% backward and binary compatible. I'd be nice
	to bump the libc minor to note that it's there, though.
