[svn-r22751] Purpose:

  HDFFV-5919 -  GMQS: h5diff - The number of object difference is not consistent between dataset and group/type when attribute(s) have differences

Description:
  Object differences are not consistent between dataset and group/datatype when their attribute(s) have differences. This is because attribute(s) differences is not accumulated to group or datatype object’s difference, but accumulated to dataset difference.
  To fix, do not accumulate attribute difference to dataset difference.  This is referred to h5diff’s default behavior and also past report from users that users were confused by the accumulated behavior. (also can’t figure out only for dataset difference , also hard to spot dataset difference when it has lots of attributes or differences)
  This also lead to fix inconsistent format indicating difference between dataset and group/datatype object.

Tested: 
    jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE),  Windows (32-LE cmake), cmake (jam)
