Purpose: Add new C++ wrappers

Description:
    Added wrappers for H5Iis_valid, H5Ps/get_nlinks, H5Tget_create_plist,
    H5Oopen, H5Oclose and H5Pset_virtual

        // Checks if the given ID is valid.
        static bool isValid(hid_t an_id);

        // Sets the number of soft or user-defined links that can be
        // traversed before a failure occurs.
        void setNumLinks(size_t nlinks) const;

        // Gets the number of soft or user-defined link traversals allowed
        size_t getNumLinks() const;

        // Returns a copy of the creation property list of a datatype.
        PropList getCreatePlist() const;

        // Opens an object within a group or a file, i.e., root group.
        hid_t getObjId(const char* name,...);
        hid_t getObjId(const H5std_string& name,...);

        // Closes an object opened by getObjId().
        void closeObjId(hid_t obj_id) const;

        // Maps elements of a virtual dataset to elements of the source dataset.
        void setVirtual(const DataSpace& vspace, const char *src_fname,...);
        void setVirtual(const DataSpace& vspace, const H5std_string src_fname,...);

Platforms tested:
    Linux/32 2.6 (jam)
    Linux/64 (platypus)
    Darwin (osx1010test)
