[svn-r20384] Purpose:

    Fixed Bug 2184 - GMQS: h5diff - incorrect calculation code for 
    --use-system-epsilon option

Description:
    Merged from HDF5 1.8 branch r20369.
    Fixed h5diff for --use-system-epsilon option: the calculation changed
    from ( |a - b| / b ) to ( |a - b| ). This was decided for better 
    performance and was corrected only in HDF5 trunk, so 1.8 got updated.
    Also comments for equal_XXX() function were updated correctly. 
    Also help page and RM got updated correctly.
    Also add test cases for testing the differences w/wo the option.

     
Tested:
 jam (linux32-LE), amani (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Windows (32-LE)
