      Variety of belt-tightenings in the bignum code. (Please help test this!) · e042540f
      Geoff Thorpe authored
      - Remove some unnecessary "+1"-like fudges. Sizes should be handled
        exactly, as enlarging size parameters causes needless bloat and may just
        make bugs less likely rather than fixing them: bn_expand() macro,
        bn_expand_internal(), and BN_sqr().
      - Deprecate bn_dup_expand() - it's new since 0.9.7, unused, and not that
        useful.
      - Remove unnecessary zeroing of unused bytes in bn_expand2().
      - Rewrite BN_set_word() - it should be much simpler, the previous
        complexities probably date from old mismatched type issues.
      - Add missing bn_check_top() macros in bn_word.c
      - Improve some degenerate case handling in BN_[add|sub]_word(), add
        comments, and avoid a bignum expansion if an overflow isn't possible.
