     * Returning sorting number for tables with a "sortby" column
     * Using when new records are created and existing records are moved around.
     *
     * The strategy is:
     *  - if no record exists: set interval as sorting number
     *  - if inserted before an element: put in the middle of the existing elements
     *  - if inserted behind the last element: add interval to last sorting number
     *  - if collision: move all subsequent records by 2 * interval, insert new record with collision + interval
     *
     * How to calculate the maximum possible inserts for the worst case of adding all records to the top,
     * such that the sorting number stays within INT_MAX
     *
     * i = interval (currently 256)
     * c = number of inserts until collision
     * s = max sorting number to reach (INT_MAX - 32bit)
     * n = number of records (~83 million)
     *
     * c = 2 * g
     * g = log2(i) / 2 + 1
     * n = g * s / i - g + 1
     *
     * The algorithm can be tuned by adjusting the interval value.
     * Higher value means less collisions, but also less inserts are possible to stay within INT_MAX.
     *
     * @param string $table Table name
     * @param int $uid Uid of record to find sorting number for. May be zero in case of new.
     * @param int $pid Positioning PID, either >=0 (pointing to page in which case we find sorting number for first record in page) or <0 (pointing to record in which case to find next sorting number after this record)
     * @return int|array|bool|null Returns integer if PID is >=0, otherwise an array with PID and sorting number. Possibly FALSE in case of error.
