[svn-r15604] The MPI compiler(mvapich2-0.9.8p2patched-intel-ofed-1.2) at NCSA's linux cluster(Abe) fails to handle collective IO calls with very complicate MPI derived datatype. All the values of input parameters from HDF5 are correct before passing to MPI-IO collective calls. Sometimes the following errors happen:

rank 0 in job 77  honest1.ncsa.uiuc.edu_60945   caused collective abort of all ranks
  exit status of rank 0: killed by signal 9

Up to this point, we decide to turn off the use of advanced MPI derived datatype features inside HDF5 so that complicated selection tests are ensured to be handled by HDF5.  This check-in reflects this.
