* This version is still sub-optimal and transfers more data amongst the
  I/O server processes than strictly necessary.

* Having a configuration object will allow future extensions without
  a change of interface to cdiPioInit.
* Also move code to translate I/O mode string vs. integer into library.

* Every server now serves a subset of the clients only.

* Also automatically find cfortran.h flag for as many platforms as we
  can test at the moment.

* r3363: merged changes from branches/cdi_fileDrivenInput

* This way the MPI parts of CDI can be compiled without introducing
  an artificial MPI dependency for non-MPI parts.

* This test currently only checks if a single missing value is
  successfully written out and counted on input.
