[svn-r6755] Purpose:
feature Description: added test_fapl_mpiposix_dup to verify the MPIPOSIX is making duplicates of Communicator correctly. Platforms tested: Did not h5committested because these are all MPI code and well protected by HAVE_PARALLEL. Tested in eirene and modi4, both parallel mode. Misc. update:
