protected function FeedsAtomRDFProcessor::existingItemIdGlobal in Feeds Atom 6

Add handler to find an id globally

Because our deletion feeds are not necessarily the same feed as the "create new" feed, we need to check for existing items across all feeds, not just the current feed. As long as the GUID is really unique that should not cause a problem.

@todo Refactor this once http://drupal.org/node/828176 gets resolved.
