Joerg Wunsch 8a173970c1 Add some special hooks for sppp(4) interfaces. In addition to the
normal ifconfig stuff, one might need to pass down authentication
parameters for them.

This is closely tied to Hellmuth's impending rc patches for ISDN, but
sppp can also be used separately (thus it doesn't go directly into the
planned ISDN section of rc.conf).
