[svn-r22032] - move all HDF5 library access for H5F routines to the native layer, higher layer only handle ids

- create a high level user id to return to users to hold vol id and object id
- all H5 callbacks implemented except for get_object_count/ids
- some bug fixes, test suite fails for now pending update to user ids of other objects
