HtmlSanitizer::apply_string_callbacks()privateWC 1.0

Applies callbacks used to process the string before and after wp_kses().

If a callback is invalid we will short-circuit and return an empty string, on the grounds that it is better to output nothing than risky HTML. We also call the problem out via _doing_it_wrong() to highlight the problem (and increase the chances of this being caught during development).
