Reorder fields and change one prototype.

The fields raised warnign of initialization out-of-order.  The prototype
said int, but it should have been void.

Removed RowScale from all versions -- the symmetric version was
bugged and could never have worked.  Removed ColumnScale from
Sym matrices and SymmetricScale from Gen matrices.
