[svn-r16062] Purpose: Allow per-dataset rdcc configuration

Description: Adds 3 new public functions: H5Pset_chunk_cache,
H5Pget_chunk_cache, and H5Dget_access_list.  First implementation of dataset
access properties.  See RFC_chunk_cache_functions for details.

Tested: kagiso, linew, smirom (h5committest)
