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
