* preauth.c (krb5_process_padata): Added generalized processing for
	preauth information which is returned by the KDC.  This should be
	general enough to support the AFS3_SALT preauth type, the SNK4
	preauth type, and the public-key mods to Kerberos.
(process_pw_salt): New function for processing the KRB5_PW_SALT
	preauthentication type.

* get_in_tkt.c (decrypt_as_reply): Removed temporary kludge for
	processing the PW_SALT preauth type; that's now done in preauth.c
(krb5_get_in_tkt): Call krb5_process_padata with new arguments so that
	the preauth code can set the decryption_key if necessary.
