[issue26536] Add the SIO_LOOPBACK_FAST_PATH option to socket.ioctl

[Daniel Stokes]

New submission from Daniel Stokes:

Adding the SIO_LOOPBACK_FAST_PATH option to socket.ioctl on Windows allows Windows users to enable the loopback fast path option available on Windows 8+. This allows for much better TCP loopback performance on Windows.
