   1 -- Add extra option fields to the ipblocks table, add some extra indexes,
   2 -- convert infinity values in ipb_expiry to something that sorts better,
   3 -- extend ipb_address and range fields, add a unique index for block conflict
   4 -- detection.
   5
   6 -- Conflicts in the new unique index can be handled by creating a new
   7 -- table and inserting into it instead of doing an ALTER TABLE.
