Description:
    Added wrappers for H5Oget_info_by_idx2.

    // Returns information about an HDF5 object, given its index.
    void getInfo(const char* grp_name, H5_index_t idx_type,
                 H5_iter_order_t order, hsize_t idx, H5O_info_t& objinfo,
                 unsigned fields = H5O_INFO_BASIC,
                 const LinkAccPropList& lapl = LinkAccPropList::DEFAULT)
    void getInfo(const H5std_string& grp_name, H5_index_t idx_type,
                 H5_iter_order_t order, hsize_t idx, H5O_info_t& objinfo,
                 unsigned fields = H5O_INFO_BASIC,
                 const LinkAccPropList& lapl = LinkAccPropList::DEFAULT)
Platforms tested:
    Linux/64 (jelly)
