Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
*) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
result in a zero length in the ASN1_INTEGER structure which was
not consistent with the structure when d2i_ASN1_INTEGER() was used
and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
where it did not print out a minus for negative ASN1_INTEGER.
[Steve Henson]
*) Fix 'openssl passwd -1'.
