 If you want to do something before/after an attachment has been uploaded -
 or replace the upload function entirely -- there doesn't seem to be a way
 to do that:

 For other `wp_ajax_* calls`, you can unhook them and then hook in your
 own. This doesn't work for `wp_ajax_upload_attachment` because it ends up
 getting called directly from async-upload.php.

 If we replace the direct call with another set of `do_action/add_action`
 (like admin-ajax has) you can now hook into upload like the other ajax
 actions.

 See the proposed patch.
