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.
