[svn-r22062] Purpose: Fix bugs in chunk cache's SWMR implementation Description: Two issues were found with the chunk cache's SWMR implementation: 1. Some places were not properly setting the rdcc field in the index udata struct. Fixed. May eventually need to add an rdcc field to the idx_info struct. 2. While recalculating the indices for chunks in a dataset being resized, it was possible for the chunk cache to attempt to flush a chunk before all the indices were updated, which caused problems when a node split and flush dependencies needed to be updated, because the child nodes could not be found in the chunk cache due to the index being out of date. Modified algorithm in H5D_chunk_update_cache to keep a temporary list of entries that got "bumped", and only evict them after all chunks have updated indices. Also modified H5D_chunk_update_flush_dep and H5D_chunk_update_flush_dep to search this temporary list when looking for the child chunk entry. As a side effect, chunks are now more likely to remain in cache after a call to H5Dset_extent (even without SWMR), so performance should improve slightly.
