Summary: when using h5diff to compare the results of h5repack (or other tools that copy one HDF5 file to another), a new option is needed to allow h5diff to make an "absolute" comparison of the 2 files. This is the "contents" mode explained in the usage below.
If this mode is present, objects in both files must match (must be exactly the same). If this does not happen, the tool returns an error code of 1 (instead of the success code of 0)
Changes to the h5repack test script: the call to h5diff was changed to include -c (maintaining the previous -q).
tested: windows, linux, solaris
The name of the files are now given by its full name relative to $srcdir
To avoid the printing of the complete full path of the test file, that hides
all the other parameters for long paths, the printing of the command line
is done first in TESTING with the name only of the test file, not its full path
the printing in the expected output that had the file name was removed as well as 3 tests that tested error messages in which the file name was present
tested: linux (in 2 different build directories relative to $srcdir), solaris
