Change S/Key stuff from using a flat file (/etc/skeykeys) to a directory

where each user gets their own file, which is owned by that user.
An old S/Key database may be converted by running "skeyinit -C" as root.
Programs that need to access the S/Key database no longer need to be
setuid root.  They must now be setgid auth instead.
