Make a note of the "up" functions.

         *) applies to 0.9.6a/0.9.6b/0.9.6c and 0.9.7

         +) applies to 0.9.7 only

  +) Give DH, DSA, and RSA types their own "**_up()" function to increment

     reference counts. This performs normal REF_PRINT/REF_CHECK macros on

     the operation, and provides a more encapsulated way for external code

     (crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code

     to use these functions rather than manually incrementing the counts.

  *) s3_srvr.c: allow sending of large client certificate lists (> 16 kB).

     This function was broken, as the check for a new client hello message

     to handle SGC did not allow these large messages.
