Fix: Python bindings array access functions write out of bounds

The array access functions in the Python complements are writing
past the last element to add a NULL pointer and then using it from the
Python code to detect the end of the array. This may cause stability
issues.

This changes the functions to return multiple values (array and length)
in Python using SWIG's built-in OUTPUT typemaps.
