be82e92fc4 Require that r and b are different for field multiplication. 
Suggested by Peter Dettman, this prepares for slightly faster muitiplication
which writes results immediately to r before finishing reading b.

b5c9ee756f Make test_point_times_order test meaningful again 
As wnaf splitting is scalar based, multiplying with the order directly
would be reduced to multiplication with zero before even converting to
wnaf.
