Subject: s3/param: Autogenerate parameters prototypes again after proto.h was
 frozen

This autogenerates the parameters so that we can keep everything in sync easier,
particularly when adding new parameters.  This will also make it easier to move
to a fully autogenerated system in the future, as it reduces special cases.
