 Enable RemoteGHCi on Windows

 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.
