If a FIFO is opened with O_RDWR access, create the pipe with
read/write access, and make the first client have the handle of that
pipe as its I/O handle.
Adjust fhandler_fifo::raw_read to account for the result of trying to
read from that client if there's no data.

The second patch in this series enables opening a FIFO with O_RDWR
access. The underlying Windows named pipe is creted with duplex
access, and its handle is made the I/O handle of the first client.
While testing this, I had some mysterious crashes, which are fixed by
the first patch.
I tested th
fhandler_fifo::clone called fhandler_base::clone on each client
fhandler. But those fhandlers are actually fhandler_fifo objects, so
when fhandler_base::clone calls copyto, it's actually
fhandler_fifo::copyto that gets called. This can lead to mysterious
crashes.
Fix this by simply calling clone
