[ovs-dev] [PATCH 3/5] socket-util: pipe for Windows.

Windows does have pipes (the interface is a little different).
We mostly use pipes in Linux to synchronize between parent and
children and also to handle fatal signals and then wake from poll_loop().

For Windows, we are using events for the same purpose. So don't
implement pipes for Windows.
