[svn-r947] Lots of patches to enable dataset region references. The testing for these
need to be finished and checked in still.

+/*-------------------------------------------------------------------------
+ * Function: H5Pset_gc_references
+ *
+ * Purpose: Sets the flag for garbage collecting references for the file.
+ * Dataset region references (and other reference types probably) use
+ * space in the file heap. If garbage collection is on and the user
+ * passes in an uninitialized value in a reference structure, the heap
+ * might get corrupted. When garbage collection is off however and the
+ * user re-uses a reference, the previous heap block will be orphaned and
+ * not returned to the free heap space. When garbage collection is on,
+ * the user must initialize the reference structures to 0 or risk heap
+ * corruption.
+ *
+ * Default value for garbage collecting references is off, just to be
+ * on the safe side.

+ Non-negative on success/Negative on failure
+ DESCRIPTION
+ This function selects array elements to be included in the selection for
+ the dataspace. The COORD array is a 2-D array of size <dataspace rank>
+ by NUM_ELEM (ie. a list of coordinates in the dataspace). The order of
+ the element coordinates in the COORD array specifies the order that the
+ array elements are iterated through when I/O is performed. Duplicate
+ coordinates are not checked for. The selection operator, OP, determines
+ how the new selection is to be combined with the existing selection for
+ the dataspace. Currently, only H5S_SELECT_SET is supported, which replaces
+ the existing selection with the one defined in this call. When operators
+ other than H5S_SELECT_SET are used to combine a new selection with an
+ existing selection, the selection ordering is reset to 'C' array ordering.
