This implementation is optimised to look whether the position is within the buffers, so as to avoid calling Python seek or tell. It is important for many applications that the overhead of calling into Python is avoided as much as possible (e.g. parsers which may do a lot of backtracking)

Update the python file to reflect the state of this stream buffer.
Empty the write buffer into the Python file object and set the seek position of the latter accordingly (C++ standard section 27.5.2.4.2). If there is no write buffer or it is empty, but there is a non-empty read buffer, set the Python file object seek position to the seek position in that read buffer.

The default size of the read and write buffer.
They are respectively used to buffer data read from and data written to the Python file object. It can be modified from Python.
