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.

- * Reference search
- * This fuction searches for existing references to a given media file
- * and returns an array with the found pages. It doesn't pay any
- * attention to ACL permissions to find every reference. The caller
- * must check if the user has the appropriate rights to see the found
- * page and eventually have to prevent the result from displaying.
- *
- * @param array  $data Reference to the result data structure
- * @param string $base Base usually $conf['datadir']
- * @param string $file current file or directory relative to $base
- * @param char   $type Type either 'd' for directory or 'f' for file
- * @param int    $lvl  Current recursion depht
- * @param mixed  $opts option array as given to search()
- *
- * $opts['query'] is the demanded media file name
