 Changes between 0.9.7c and 0.9.8  [xx XXX xxxx]

  *) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and
     remained unused and not that useful. A variety of other little bignum
     tweaks and fixes have also been made continuing on from the audit (see
     below).
     [Geoff Thorpe]

  *) Constify all or almost all d2i, c2i, s2i and r2i functions, along with
     associated ASN1, EVP and SSL functions and old ASN1 macros.
     [Richard Levitte]

  *) BN_zero() only needs to set 'top' and 'neg' to zero for correct results,
     and this should never fail. So the return value from the use of
     BN_set_word() (which can fail due to needless expansion) is now deprecated;
     if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro.
     [Geoff Thorpe]

  *) BN_CTX_get() should return zero-valued bignums, providing the same
     initialised value as BN_new().
