I wonder why there are some ui/si variants for mpz_kronecker, but not for the
simpler functions mpz_jacobi and mpz_legendre.
Assume one wants to compute the Legendre symbol (A/P) for P an unsigned long
(and A too). What is more efficient?
1) use mpz_kronecker_ui, which forces to convert A to unsigned long
2) use mpz_ui_kronecker, which forces to convert P to unsigned long
3) use mpz_legendre, which forces to convert both A and P to unsigned long
