[f2py] Outputting unknown size arrays

AFAIR the only possibility to achieve this is via allocatable module
data.  That means that you need a Fortran 90 interface module
function to allocate this and, to be clean, an additional python
interface function to pass this allocated array back to the caller.
Please refer to the user guide on how to access module level
allocatable arrays.
