Define the OPENSSL_ITEM structure.

 Changes between 0.9.7a and 0.9.8  [xx XXX xxxx]

  *) Add a generic structure called OPENSSL_ITEM.  This can be used to

     pass a list of arguments to any function as well as provide a way

     for a function to pass data back to the caller.

     [Richard Levitte]

  *) Add the functions BUF_strndup() and BUF_memdup().  BUF_strndup()

     works like BUF_strdup() but can be used to duplicate a portion of

     a string.  The copy gets NUL-terminated.  BUF_memdup() duplicates
