* k5-int.h (krb5_ser_handle): Now points to const.

(krb5_kt_dfl_ops): Now const.
(struct _krb5_kt_ops): Field serializer now points to const krb5_ser_entry
instead of void.
* krb5.hin (struct _krb5_kt): Field ops now points to const.
* kt_file.c (krb5_ktf_ops, krb5_ktf_writable_ops): Now const.  Drop cast of
serializer entry initializer.
(fopen_mode_rbplus, fopen_mode_rb): Now const.
* kt_srvtab.c (krb5_kts_ops): Now const.
* ktbase.c (krb5_ktf_ops, krb5_kts_ops): Update declarations.
(struct krb5_kt_typelist): Field ops now points to const.
