History
David Benjamin 2bf82975ad Make bn_mul_part_recursive constant-time. 
This follows similar lines as the previous cleanups and fixes the
documentation of the preconditions.

And with that, RSA private key operations, provided p and q have the
same bit length, should be constant time, as far as I know. (Though I'm
sure I've missed something.)

bn_cmp_part_words and bn_cmp_words are no longer used and deleted.
