[svn-r15959] Description:

    Added missing wrappers for H5Rdereference.
    Also, for these wrappers, improved exception handlings to report specific
        overloaded functions, where failure occurs.  Will do the same for more
        functions later...

Platforms tested:
    Linux 2.6 (kagiso)
    SunOS 5.10 (linew)
    FreeBSD (duty)
