[svn-r5168]
Purpose:
H5Dset_extent API function
Description:
1 new public function: H5Dset_extent, that allows shrinking a dataset
several private functions that free the previously allocated chunks
H5F_istore_prune_by_extent, H5B_prune_by_extent : removes the chunks
H5F_istore_initialize_by_extent : initializes them with the fill value
H5S_select_fill is used to fill the selection in the memory buffer
