Adjust array/scalar promotion to handle rationals and complex numbers.
As discussed in #6581, genrand and fill_array functions cannot be
used together, without reinitializing the state.

This commit removes wrappers around DSFMT's fill_array
functions. It is easy enough to add them back if required at a later
point.
