Fix crash on empty TXT records
In k5_try_realm_txt_rr(), error out if the first text string in a TXT
record is empty or if its length exceeds the record length.
This function is only used when dns_lookup_realm is set to true in
krb5.conf. An alternative implementation is used on Windows.
[ghudson@mit.edu: moved zero-length check and added upper bound check;
