* f_cksum.c: Change code to match prototypes

    * f_cksum.c: Change code to match prototypes

	* f_cbc.c, f_ecb, f_parity, f_pcbc: Change des_cblock to
		mit_des_cblock and  des_key_schedule to
		mit_des_key_schedule. Also include des_int.h.

	* destest.c: Change des_cblock to mit_des_cblock and add local
		prototypes.

	* cs_entry.c: Remove prototypes for mit_des_cbc_cksum and
		mit_des_cbc_cksum. Now in des_int.h.

	* cbc_cksum.c, string2key.c:	Remove casts in call to
		mit_des_cbc_cksum

	* des_int.h: Add prototype for mit_des_cbc_verf_cksum. Change
		return code for mit_des_cbc_cksum to match source.

	* des.h: Remove unused structures and defines.

Short end - fix des_int.h to reflect reality (i.e. source code) and then
fix rest of code to agree. Also removed the use of old structures such
as des_cblock and  des_key_schedule. Instead the the newer
mit_des_cblock and mit_des_schedule are used.
