parallel netcdf version info

[Jim Edwards]

I gave it a try to write something into configure but then realized that I
would need to be able to link mpi in order to call the
ncmpi_inq_libvers function which is something that you cannot do from
configure on all platforms.     I added a call in my libraries init function
to that function so that I will get a runtime failure with a descent error
message if the version is too old.

As for the f90 interface - I'm afraid what you have there won't work.   All
of the subroutines should be functions and you are
missing the interface I am using - the  nfmpi_get_var_all and
nfmpi_put_var_all types.    I'm not sure yet but I think that I have
something that will generate the f90 interfaces from a template file - let
me give it a little thought, I may be able to contribute something here.
