Final cleanup pass in BN_div

Tidy up the setup. Also we can simplify all the sign management. If snum
and sdiv just preserve the sign bits of numerator and denominator, the
remainder will have the correct sign from the start.

(The original code called BN_cmp and BN_add in places, which is
sensitive to the sign.)
