Change pingback/trackbacks to use new HTTP API
|Reported by:||Otto42||Owned by:||jacobsantos|
The pingback and trackback functions are still using direct socket connections to perform their tasks. These are problematic on some servers, and they need to be changed over to the new HTTP API to let them work in more places.
Conversion should be relatively straightforward in most cases, using the new wp_remote_get and wp_remote_post and such.
