Trac 11100 expose part of create pipe

Makes the needed changes to make RemoteGHCi work on Windows.
The approach passes OS Handles areound instead of the Posix Fd
as on Linux.
The reason is that I could not find any real documentation about
the behaviour of Windows w.r.t inheritance and Posix FDs.
The implementation with Fd did not seem to be able to find the Fd
in the child process. Instead I'm using the much better documented
approach of passing inheriting handles.
This requires a small modification to the `process` library.
