[svn-r20794] Purpose:

    HDFFV-5928 - GMQS: h5diff problem and improvement on comparsing the same objects

Description:
    Merged from HDF5 trunk r20767.
    Improved performance by eliminating duplicated action for getting object 
    information in half from the previous fixe when comparing group vs group. 
    This is addition to the previous commit r20706.

Tested:
    jam (linux32-LE), koala (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE)
