Comments: In wp_xmlrpc_server::pingback_ping():

Browse Source 
* Rename `$linea` to `$remote_source` for clarity. 
* Add `remote_source` to comment data, so it's available to `preprocess_comment` and `comment_post` filters.
* Pass the original (unfiltered) response source to the filters too (as `remote_source_original` in comment data).

Props dshanske for the original patch.
Fixes #34141.
