[svn-r5435] Purpose:
Document Code improvement below: Description: Propagated the "fill time" property into the parallel chunk allocation routine, allowing it to avoid writing fill values to each new chunk allocated. This improves the performance of chunked datasets in parallel I/O to be on par with contiguous datasets again (on modi4).

New Features
============
+ * Added feature to parallel chunk allocation routine to not write fill
+ values to chunks allocated if the user has set the "fill time" to never.
+ This can improve parallel I/O performance for chunked
+ datasets. QAK - 2002/05/17
* Changed method for allocating chunked dataset blocks in parallel to only
allocate blocks that don't already exist, instead of attempting to create
all the blocks all the time. This improves parallel I/O performance for
