[svn-r3122] Purpose:

Fix and improve

Description:
        - Put functions that are common to H5File and Group into a
          prototype class, CommonFG.  I didn't do that before because
          of the fear of the consequences of multiple inheritance, since
          H5File and Group already inherit from different super classes.
          I recently read a C++ book and learned to use MI more safely.
          This change reduced some more of code redundancy.
        - Added missing const to some function parameters

Platforms tested:
        Solaris/CC 5.0 (arabica)
