[svn-r7057] Purpose:
    Bug fix, refactored code

Description:
    Fixed closing objects for "strong" file degree, which previously would
sometime attempt to close the same object twice (when a named datatype and
a dataset which used it were both left open before the file was closed).

    Stopped datatype iteration from querying for the group entry of non-named
datatypes.

    Added attributes to the list of objects that can be queried by
H5Fget_obj_count and H5Fget_obj_ids, since they can hold open a file also.

    Took a suggestion from Robb to return the number of open objects
in the return values of H5Fget_obj_count and H5Fget_obj_ids.

    Also, added a "max_objs" parameter to the H5Fget_obj_ids function, so that
it can work well with staticly allocated arrays.


Platforms tested:
    FreeBSD 4.8 (sleipnir)
