[svn-r16589] merged from trunk: 16588
1. #1487 (B1) DS memory leaks ISSUE 1: On a "go to" error condition, previously allocated buffers were not freed. NOTE: these are "potential" memory leaks because typically the error conditions do not occur, so the potential memory leaks also do NOT occur. ISSUE 2: A function used to read dimension scales realistic data (topography of the North Atlantic, latitude and longitude) was being called without the data buffer being freed. SOLUTION FOR ISSUE 1: added "free" calls for the allocated buffers on the error sections. SOLUTION FOR ISSUE 2: added a "free" call after the read_data function, after using the buffer (on a H5Dwrite and H5Screate_simple). The read_data function reads both data and dimensions from the ASCII data files. DOCS: no docs added. Done for 1.9 and 1.8 STATUS: Closed bug tested: h5committest

- * Function: H5DSiterate_scales
- *
- * Purpose: H5DSiterate_scales iterates over the scales attached to dimension DIM
- * of dataset DID. For each scale in the list, the visitor_data and some
- * additional information, specified below, are passed to the visitor function.
- * The iteration begins with the IDX object in the group and the next element
- * to be processed by the operator is returned in IDX. If IDX is NULL, then the
- * iterator starts at zero.
- *
- * Parameters:
- *
- * hid_t DID; IN: the dataset
- * unsigned int dim; IN: the dimension of the dataset
- * int *idx; IN/OUT: input the index to start iterating, output the
- * next index to visit. If NULL, start at the first position.
- * H5DS_iterate_t visitor; IN: the visitor function
- * void *visitor_data; IN: arbitrary data to pass to the visitor function.
- *
- * Iterate over all scales of DIM, calling an application callback
- * with the item, key and any operator data.
- *
- * The operator callback receives a pointer to the item ,
- * and the pointer to the operator data passed
- * in to H5SL_iterate ('op_data'). The return values from an operator are:
- * A. Zero causes the iterator to continue, returning zero when all
- * nodes of that type have been processed.
- * B. Positive causes the iterator to immediately return that positive
- * value, indicating short-circuit success.
- * C. Negative causes the iterator to immediately return that value,
- * indicating failure.

+* Function: H5DSiterate_scales
+*
+* Purpose: H5DSiterate_scales iterates over the scales attached to dimension DIM
+* of dataset DID. For each scale in the list, the visitor_data and some
+* additional information, specified below, are passed to the visitor function.
+* The iteration begins with the IDX object in the group and the next element
+* to be processed by the operator is returned in IDX. If IDX is NULL, then the
+* iterator starts at zero.
+*
+* Parameters:
+*
+* hid_t DID; IN: the dataset
+* unsigned int dim; IN: the dimension of the dataset
+* int *idx; IN/OUT: input the index to start iterating, output the
+* next index to visit. If NULL, start at the first position.
+* H5DS_iterate_t visitor; IN: the visitor function
+* void *visitor_data; IN: arbitrary data to pass to the visitor function.
+*
+* Iterate over all scales of DIM, calling an application callback
+* with the item, key and any operator data.
+*
+* The operator callback receives a pointer to the item ,
+* and the pointer to the operator data passed
+* in to H5SL_iterate ('op_data'). The return values from an operator are:
+* A. Zero causes the iterator to continue, returning zero when all
+* nodes of that type have been processed.
+* B. Positive causes the iterator to immediately return that positive
+* value, indicating short-circuit success.
+* C. Negative causes the iterator to immediately return that value,
+* indicating failure.
