[svn-r22235] Purpose: Fixed bugs HDFFV-2761 & HDFFV-7852

Description:
    - Replaced PredType::NotAtexit() with PredType::AtExit(H5CPP_EXITED);
      and used PredType::AtExit as a flag to detect when all predefined
      types have been destroyed.  Then, H5close will be called to terminate
      the library after its being re-initiated when the PredType destructors
      were activated.  This change removed the memory leaks shown by the
      user's sample program.
    - Added H5CPP_EXITED for PredType::AtExit to use as a flag
    - Updated some inaccurate comments
    - Removed stream functions from FileAccPropList
    - Replaced H5_VMS with appropriate macro in H5IdComponent.cpp
    - Corrected many URLs (hdfgroup vs. ncsa) in comments
    - Replaced std::string with H5std_string in comments
Platforms tested:
    Linux/32 2.6 (jam)
    Linux/64 2.6 (amani)
    SunOS 5.10 (linew)
