Subject: [PATCH] Remove search_references() and the refshow configuration
 option

The refshow configuration option wasn't used as described anymore
already in the latest release and after the introduction of the media
usage index the parameter is also no longer relevant for internal
optimization. The only place where it was still used is the no longer
used search_references()-function which is removed here, too.
