* fhandler.h (class fhandler_base): Add virtual function
get_io_handle_cyg() to get handle from which OPOST-processed output is
read on PTY master.

handle to which OPOST-processed output is written. Add two functions,
i.e., set_output_handle_cyg() and get_output_handle_cyg(), regarding
variable output_handle_cyg. Now, output_handle is used only by native
windows program. The data before OPOST-processing is written to
output_handle and OPOST-processing is applied in the master-side. For a
cygwin process, OPOST-processing is applied in the slave-side, and the
data after OPOST-processing is written to output_handle_cyg.
(class fhandler_pty_master): Add two variables, i.e., io_handle_cyg and
to_master_cyg, to store handles of a pipe through which OPOST-processed
output passes. Add pty_master_fwd_thread and function
pty_master_fwd_thread() for a thread which applies OPOST-processing
and forwards data from io_handle to to_master_cyg. Add function
get_io_handle_cyg() regarding variable io_handle_cyg. Now, the pipe
between io_handle and to_master are used only by native windows program
for applying OPOST-processing in the master-side. For a cygwin process,
the pipe between io_handle_cyg and to_master_cyg is used for passing
through the data which is applied OPOST-processing in the slave-side.

than output_handle.

message. Terminate master forwarding thread. Close handles
to_master_cyg and io_handle_cyg.

(fhandler_pty_master::pty_master_thread): Add code for duplicating
handle to_master_cyg.
(fhandler_pty_master::pty_master_fwd_thread): New function for a thread
to forward OPOST-processed data from io_handle to to_master_cyg. This
thread applies OPOST-processing to the output of native windows program.
(::pty_master_fwd_thread): Ditto.
(fhandler_pty_master::setup): Create a new pipe to pass thruegh OPOST-
processed output. Create new thread to forward data from io_handle to
to_master_cyg. Set handle to_master_cyg to tty. Print io_handle_cyg as
well in debug message. Close handles io_handle_cyg and to_master_cyg in
case of error.

tty. Copy handle to_master_cyg from arch->to_master_cyg.
(fhandler_pty_master::fixup_after_exec): Clean up to_master_cyg.
* select.cc: Check handle returned by get_io_handle_cyg() rather than
get_handle().
* tty.h (class tty): Add variable _to_master_cyg to store a handle to
which OPOST-processed data is written. Add two functions,
to_master_cyg() and set_to_master_cyg(), regarding _to_master_cyg.
