+ *) Change type of various DES function arguments from des_cblock
+ (which means, in function argument declarations, pointer to char)
+ to des_cblock * (meaning pointer to array with 8 char elements),
+ which allows the compiler to do more typechecking; it was like
+ that back in SSLeay, but with lots of ugly casts.
+
+ Introduce new type const_des_cblock.

*) Reorganise the PKCS#7 library and get rid of some of the more obvious
problems: find RecipientInfo structure that matches recipient certificate
and initialise the ASN1 structures properly based on passed cipher.
