We need the INCREF here, because if our Python caller drops their
reference to py after this function has been called there may still be
something else that's using the Subversion stream object and we thus
need to make sure that the python object stays around until the svn
stream is closed. If we don't do this then calls to
svn_stream_read/svn_stream_write may end up accessing a python object
that has already been freed.
Note that the py_stream_close callback decreases the reference counter
so there should be no leaking here at the moment.
