* ktest.c (ktest_make_sample_etype_info): Use KRB5_ETYPE_NO_SALT

    * ktest.c (ktest_make_sample_etype_info): Use KRB5_ETYPE_NO_SALT
        instead of -1.

        * ktest_equal.c (ktest_equal_krb5_etype_info_entry): Test for
        KRB5_ETYPE_NO_SALT. ktest_equal_array_of_octet() and
        ktest_equal_array_of_char take unsigned int lengths.

        * ktest_equal.h: Add len_unsigned_array macro for a prototype of a
        function taking an unsigned int
        count. ktest_equal_array_of_octet() is one of
        these. ktest_equal_array_of_char() takes an unsigned int as
        length.

        * trval.c (trval): Unsigned/signed int fix.

        * utility.c (asn1_krb5_data_unparse): Better test for krb5_data
        length being less than zero.
