  A "Get next" function for partition iterator.

  SYNOPSIS
    partition_iter_func()
      part_iter  Partition iterator, you call only "iter.get_next(&iter)"

  DESCRIPTION
    Depending on whether partitions or sub-partitions are iterated, the
    function returns next subpartition id/partition number. The sequence of
    returned numbers is not ordered and may contain duplicates.

    When the end of sequence is reached, NOT_A_PARTITION_ID is returned, and 
    the iterator resets itself (so next get_next() call will start to 
    enumerate the set all over again).

  RETURN 
    NOT_A_PARTITION_ID if there are no more partitions.
    [sub]partition_id  of the next partition

  For the user, the only meaningful field is get_next, which may be used as

             part_iterator.get_next(&part_iterator);
  
  Initialization is done by any of the following calls:
    - get_partitions_in_range_iter-type function call
    - init_single_partition_iterator()
    - init_all_partitions_iterator()
  Cleanup is not needed.

                           NO_MAX_RANGE
      part_iter            Iterator structure to be initialized

  DESCRIPTION
    Functions with this signature are used to perform "Partitioning Interval
    Analysis". This analysis is applicable for any type of [sub]partitioning 
    by some function of a single fieldX. The idea is as follows:
    Given an interval "const1 <=? fieldX <=? const2", find a set of partitions
    that may contain records with value of fieldX within the given interval.

    The min_val, max_val and flags parameters specify the interval.
    The set of partitions is returned by initializing an iterator in *part_iter

  NOTES
    There are currently three functions of this type:
     - get_part_iter_for_interval_via_walking
     - get_part_iter_for_interval_cols_via_map
     - get_part_iter_for_interval_via_mapping

  RETURN 
    0 - No matching partitions, iterator not initialized
    1 - Some partitions would match, iterator intialized for traversing them
   -1 - All partitions would match, iterator not initialized
