-- Add extra option fields to the ipblocks table, add some extra indexes,
-- convert infinity values in ipb_expiry to something that sorts better,
-- extend ipb_address and range fields, add a unique index for block conflict

-- Conflicts in the new unique index can be handled by creating a new
-- table and inserting into it instead of doing an ALTER TABLE.
