[svn-r4345] Purpose:

Improvement
Description:
    The stdout and stderr were both redirected to an output file. This
    works fine in tradition sequential Unix machines.  But in some
    parallel systems (like mpi-jobs in IBM SP), the stderr is merged
    with stdout alright but not in the exact order as expected.  This
    is not deterministic in parallel jobs.  So, the test output are
    all there but the ordering maynot be as expected.
Solution:
    Redirect stderr to separated file and append it to the stdout
    file after test-command is executed.  Then compare it with
    the expected output.  This eliminate the assumption that
    stdout and stderr must merged in "chronical orders".

    The .ddl file are updated by moving all stderr text to the end of the
    file.
Platforms tested:
    eirene.
