* dtable.cc (dtable::select_write): Add missing argument to debug_printf.

Browse Source 
* fhandler.cc (fhandler_base_overlapped::setup_overlapped): Explicitly set
io_pending to false.
(fhandler_base_overlapped::has_ongoing_io): Call GetOverlappedResult to force
completion of I/O.
(fhandler_base_overlapped::wait_overlapped): Rewrite to correctly deal with
nonblocking reads and to make more race proof.
(fhandler_base_overlapped::raw_write): Deal with new enum values.
(fhandler_base_overlapped::raw_read): Ditto.  Don't deal with ongoing I/O here
since it makes no sense in the read context.
* fhandler.h (enum wait_return): Add overlapped_unknown,
overlapped_nonblocking_no_data.
* pipe.cc (pipe): Add debugging output.
