* There is still work to reconcile C++ header changes with the interface
  generators.

merged trunk into cdi_conversion_c++ and changed type of len in function serializeStrTabGetSize() to int, removed anonymous function in serializeStrTabGetSize() and replaced it with &len

* r3363: merged changes from branches/cdi_fileDrivenInput

* Also cleans up minor issues.

* This way CDI can still be built with pgcc 11.x.

* Also extend Fortran 2003 interface generator accordingly.

* Add proper formatting of example program output.
* Add test to ensure the examples are working.
* Add better handling of Pointer arguments.
* Add better handling of C char * return values.
* Add helper function for C character length.
* Test that the compiler properly support Fortran/C interop at configure
  time.
