Make /etc/rc.d/ttys run after /etc/rc.d/bootconf.sh,
because bootconf could conceivably change /etc/ttys.

Don't try to chmod ptys if we have none.

Add an _rc_subr_loaded variable, set to ":" by rc.subr. Scripts can use this
for a speedup by doing:
$_rc_subr_loaded . /etc/rc.subr

reset perms of ptyX[0-9a-zA-Z] instead of just ptyX[0-9a-f]

setup tty[p-uw-zP-T]? (kern.maxpty default = 256) instead of just tty[p-s]?.
on platforms which don't reserve ttyv? for console on ttyv0, set up ttyv?

Use load_rc_config() (from rc.subr) instead of sourcing /etc/rc.conf.
This allows us or a user to change the configuration file method in
one place - rc.subr - without having to edit all of the rc.d/
