Rename bn_mul_words()/bn_mul_add_words().

Most bn_.*_words() functions operate on two word arrays, however
bn_mul_words() and bn_mul_add_words() operate on one word array and
multiply by a single word. Rename these to bn_mulw_words() and
bn_mulw_add_words() to reflect this, following naming scheme that we use
for primitives.

This frees up bn_mul_words() to actually be used for multiplying two word
arrays. Rename bn_mul_normal() to bn_mul_words(), which will then become
one of the possible assembly integration points.
