[svn-r14247] Description:
- Refactored H5D_flush to use H5I_search for iterating through
datasets, instead of building array of dataset IDs.
- Cache dataset's dataspace modifications (from calls to
H5Dset_extent) until flush/close.
These changes give an ~15% improvement in speed for my "append records
to lots of 1-D datasets" benchmark.
