[svn-r25640] Purpose: Fixed HDFFV-4259

Description:
    - Used H5I_INVALID_HID instead of 0 to initialized member "id" in classes
      that represent HDF5 objects.  For PropList, H5P_DEFAULT has to be used
      instead of H5I_INVALID_HID.
    - Added try/catch block to some dynamically allocating memory code and
      re-throw the bad_alloc exception with a message informing the location of
      the failure.
Platforms tested:
    Linux/ppc64 (ostrich)
    Linux/32 2.6 (jam)
    SunOS 5.11 (emu)
