[svn-r6583]

Purpose: New tool

Description: Pankaj created h5import tool long time ago. I am finally checking
             the source code in for the 1.6 release.
             Known problems: h5import test will crash if srcdir option
                             is used; will be fixed before the release.

Solution:

Platforms tested: vebena, arabica, modi4 were tested. h5import tests passed
                  I also tested on arabica with srcdir option to make sure that
                  there is a problem when srcdir is used. After that I disabled
                  h5import tests. Daily tests will build h5import, but will not run
                  h5import tests.
