From edf0bfb52b46bb9c8bf44e9c486be60c7087618c Mon Sep 17 00:00:00 2001

Subject: Change type of various DES function arguments from des_cblock
 (meaning pointer to char) to des_cblock * (meaning pointer to array with 8
 char elements), which allows the compiler to do more typechecking.  (The
 changed argument types were of type des_cblock * back in SSLeay, and a lot of
 ugly casts were used then to turn them into pointers to elements; but it can
 be done without those casts.)

Introduce new type const_des_cblock -- before, the pointers rather
than the elements pointed to were declared const, and for
some reason gcc did not complain about this (but some other
compilers did).
