[svn-r12795] Purpose: Fixing bug

Description:
    Wrappers of H5Rcreate had incorrect prototypes.

Solution:
    Added these overloaded functions for H5Rcreate wrapper to IdComponent:
        void reference(void* ref, const char* name, DataSpace& dataspace,
                        H5R_type_t ref_type = H5R_DATASET_REGION) const;
        void reference(void* ref, const char* name) const;
        void reference(void* ref, const H5std_string& name) const;

    Added these overloaded functions for H5Rdereference:
        void dereference(IdComponent& obj, void* ref);
        DataSet(IdComponent& obj, void* ref);
        Group(IdComponent& obj, void* ref);
        DataType(IdComponent& obj, void* ref);

    The incorrect wrappers will be removed after announcing.

Platform tested:
    Linux 2.4 (heping)
    AIX 5.1 (copper)
    SunOS 5.8 64-bit (sol)
