Add new H5R API that abstracts object, region and attribute reference types
Also support references to external files Add new H5T_REF type and type conversion routines Support conversion from H5T_REF_OBJ/DSET_REG to H5T_REF Add H5Treclaim() API to reclaim memory of vlen/reference types Deprecate H5Dvlen_reclaim() Fix H5T_vlen_reclaim() and H5T_reclaim() to use private callback Add H5T_ref_reclaim() Move previous H5R APIs to H5Rdeprec.c Clean up H5Ocopy Separate H5O_copy_expand_ref() to H5Ocopy_ref() Add support for copying new reference types Clean up deprecated routines to go through VOL and same code path Fix return codes in existing trefer.c test Rename trefer.c to trefer_deprec.c trefer.c is for new references Add performance test for trefer Add additional obj_copy_ref test Make use of tokens and blobs to store references Skip blob encoding for object references Start adding new reference examples
