    src/plugin.[ch]: Added support for "filter" callbacks.
    This type of callback is very similar to write callbacks:
      int (*) (const data_set_t *, value_list_t *)
    The return value of that callback indicates what further actions are to be
    taken. It may be a bitwise OR of any of the following new flags:
    FILTER_NOWRITE or FILTER_NOTHRESHOLD_CHECK. If both flags are used (which
    equals the flag FILTER_IGNORE), the value list is ignored completely.
    If more than one such callback is available, the respective return values are
    bitwise OR'ed. If they "sum" up to FILTER_IGNORE, no further callbacks are
    executed (lazy evaluation).
    This type of callback may be used for the following purposes:
     * rewrite information included in the value list (e.g. the instance
     * discard certain information on a fine-grained level based on the
       information provided by the data set and value list
