Modified Files:
        src/sbin/cgdconfig: cgdconfig.8 cgdconfig.c

Log Message:
cgdconfig(8): Handle -P/-S for shared keys with -G too.

This way you can convert an existing parameters file to one that is
derived from a shared key, and derive other subkeys for other disks
from the same shared key.

        cgdconfig -G -S -o /etc/cgd/wd0.shared /etc/cgd/wd0
        cgdconfig -G -S -o /etc/cgd/wd1.shared \
                -P /etc/cgd/wd0.shared /etc/cgd/wd1

This way, if you enter the same new password both times, wd0.shared
and wd1.shared generate the same keys as wd0 and wd1, but only need
one password entry with `cgdconfig -C'.
