[svn-r1374] Added in code to support the H5Diterate function, which I've got to add tests

for now.  Also, I revised some of the code for hyperslab I/O, which should
provide a modest speedup in situations with lots of hyperslabs.

+ NAME
+    H5S_none_select_iterate
+ PURPOSE
+    Iterate over a none selection, calling a user's function for each
+        element. (i.e. the user's function is not called because there are
+        zero elements selected)
+ USAGE
+    herr_t H5S_none_select_iterate(buf, type_id, space, operator, operator_data)
+        void *buf;      IN/OUT: Buffer containing elements to iterate over
+        hid_t type_id;  IN: Datatype ID of BUF array.
+        H5S_t *space;   IN: Dataspace object containing selection to iterate over
+        H5D_operator_t operator; IN: Function pointer to the routine to be
+                                called for each element in BUF iterated over.
+        void *operator_data;    IN/OUT: Pointer to any user-defined data
+                                associated with the operation.
+ RETURNS
+    Returns success (0).
