Adrian Dewhurst 9c04e30735 util/dnsname: do not allow labels starting with a digit ...

This disallows labels that start with digits (as per RFC 1035 section
2.3.1). The invalid character error text is also improved so that UTF-8
sequences are properly copied to the error rather than an encoding of
the first byte.

Updates #13858
