 Related to #34141, which would pass the retrieved pingback source to
 preprocess_comment and comment_post for additional processing,
 pingback_ping currently strips all content from the source as part of its
 processing.

 Suggesting that specifically:

 1. Sanitization be done using core sanitization functions(wp_kses, etc)
 2. The code that returns relevant errors(URL not found, etc), be processed
 ahead of anything else.
 3. The older code that duplicates the functionality of url_to_postid noted
 as FIXME be removed. If there really is another difference, that should be
 an enhancement to url_to_postid.

 This, combined with the enhancements in #34141, would allow moving toward
 improving linkback presentation(#32653), which is a long term goal.
