[issue18100] socket.sendall() cannot send buffers of 2GB or more

[Tom van Leeuwen]

New submission from Tom van Leeuwen:

When using socket.sendall() to send a buffer of 2GB or more (for example, numpy.zeros(2*GB, dtype=numpy.uint8) ), it doesn't send anything at all.

In socketmodule.c, socket.sendall() sock_sendall uses an int for len, while this should be a Py_ssize_t.
