Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
*) Constify the ENGINE code as a result of BIGNUM constification.
+ Also constify the RSA code and most things related to it. In a
+ few places, most notable in the depth of the ASN.1 code, ugly
+ casts back to non-const were required (to be solved at a later
+ time)
