* Makefile.in: Removed rd_req_sim.c

	* Makefile.in: Removed rd_req_sim.c

	* auth_con.c: Default cksumtype is now CKSUMTYPE_RSA_MD4_DES.

	* auth_con.c: Added krb5_auth_con_setuseruserkey(),
		krb5_auth_con_getkey(),
		krb5_auth_con_getremotesubkey(),
		krb5_auth_con_getauthenticator(),
		krb5_auth_con_getremoteseqnumber(),
		krb5_auth_con_initivector().

	* auth_con.c: Fixed krb5_auth_con_getlocalsubkey() to check for
		a valid local_subkey before calling krb5_copy_keyblock().

	* auth_con.h: Fixed some comments.

	* mk_req_ext.c (krb5_mk_req_extended()): Always pass in a seed
		(the keyblock contents) to krb5_calculate_checksum()

	* rd_rep.c (krb5_rd_rep()): Use appropriate key to decode reply.

	* rd_safe.c (krb5_rd_safe()): Don't pass checksum to
		krb5_rd_safe_basic(), it's unnecessary.

	* compat_recv.c (krb5_compat_recvauth()):
	* mk_rep.c (krb5_mk_rep()):
	* rd_req.c (krb5_rd_req()):
	* rd_req_dec.c (krb5_rd_req_decode()):
	* recvauth.c (krb5_recvauth()):
		Added a krb5_auth_context argument and eliminated many of
		the other arguments because they are included in the
		krb5_auth_context structure.
