[svn-r8903] Purpose:

h5diff and h5repack changes

Description:
h5diff
introduced the following four modes of output:
 Normal mode: print the number of differences found and where they occured
  Report mode: print the above plus the differences
   Verbose mode: print the above plus a list of objects and warnings
    Quiet mode: do not print output (h5diff always returns an exit code of 1 when differences are found)

    h5repack
     added an extra parameter for SZIP filter (coding method)
     the new syntax is
     -f SZIP=<pixels per block,coding>
     (pixels per block is a even number in 2-32 and coding method is 'EC' or 'NN')
     Example of use:
     ./h5repack -i file1 -o file2 -f SZIP=8,NN -v

     updated usage messages, test scripts and files accordingly



Solution:

Platforms tested:
linux
solaris
AIX
