[svn-r10212] Purpose: Added more wrappers

Description:
    Added the following to the C++ library
        + overloaded functions:
                string CommonFG::getObjnameByIdx(hsize_t idx)
                H5T_order_t AtomType::getOrder()
        + wrappers for H5*close
        + wrappers for H5Arename, H5Aget_storage_size, and H5Dget_storage_size

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