[svn-r5662] Purpose:
Bug fix. Description: The chunking code was using internal allocation routines to put blocks on a free list for reuse, instead of using the system allocation routines (ie. malloc, free, etc.). This causes problems when user filters attempt to allocate/free chunks for their algorithm's use. Solution: Switched the chunking code back to using the system allocation routines, we can address performance issues with them if it becomes a real problem. Platforms tested: Linux 2.2.x (eirene) && IRIX64 6.5 (modi4)

-------
+ * Fixed bug in chunking routines where they were using internal allocation
+ free routines, instead of malloc/free, preventing user filters from
+ working correctly. Chunks are now allocated/freed with malloc/free and
+ so should the chunks in user filters. QAK 2002/06/18
* Fixed bug where regular hyperslab selection could get incorrectly
transferred when the number of elements in a row did not fit evenly
into the buffer provided. QAK 2002/06/12
