[svn-r22188] Purpose:

  Fix for HDFFV-7644 GMQS: h5diff - incorrect behaviors when comparing HDF5 files with different type of objects (dataset, group, type) as common objects

Description:
  Fixed failure for comparing same named object with different object types in comparing groups. (common object comparison)
  Prior to the fix, h5diff resulted in error. After the fix, h5diff detects such case as non-comparable and display messages accordingly.
  Test cases were added and tagged with jira#.
  Merged from HDF5 trunk 22176.

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