Because of the DNS name encoding, the consumed bytes in the tvb and the length of the string of the dns name can be different. We need to handle them separately for the purpose they are. Moreover the name string can contain null bytes, then we can't rely on strlen() but we need the actual length. Subsequent calls to proto_tree_add_string() will require to pass the string to format_text() in order have non-printable characters printed.
