[svn-r5170]

Purpose:
    New feature
Description:
    Fill-value's behaviors for contiguous dataset have been redefined.
    Basicly, dataset won't allocate space until it's necessary.  Full details
    are available at http://hdf.ncsa.uiuc.edu/RFC/Fill_Value, at this moment.
Platforms tested:
    Linux 2.2.
