bulletproofs: multiply points by 8 first thing in verification
instead of merging that with other scalar multiplications
where possible for speed, since this is not actually safe

bulletproofs: reject x, y, z, or w[i] being zero
Also try again when we're generate a proof with those characteristics

bulletproofs: a few fixes from the Kudelski review
- fix integer overflow in n_bulletproof_amounts
- check input scalars are in range
- remove use of environment variable to tweak straus performance
- do not use implementation defined signed shift for signum
