Bruce Evans b62d102cbb Uniformized pr_ctlinput protosw functions. The third arg is now `void
*' instead of caddr_t and it isn't optional (it never was).  Most of the
netipx (and netns) pr_ctlinput functions abuse the second arg instead of
using the third arg but fixing this is beyond the scope of this round
of changes.
