* This change creates an archive containing resource_unpack.c only for
  use in test programs.

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

* Also compare uuid in grid comparison.

* 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.

* And use that if available.

* It's at the moment identical to the 1D test. That will change with the next commit.

* This also adds separate documentation, header, Fortran wrappers and
  pkg-config file for the cdi-pio part of the library

* This will allow for later additions of more complex tests.

* Makefile.am became desynchronized from Makefile.in.

This reverts commit r2206.

This reverts commit r2212.

* Also add streamWriteVarPart to public API.

* This ensures dependencies on the library are generated.
