What changed:
-------------
- The maximum number of PTYs has been raised from 64 to 128.
Bug Fixes
---------
- Fix potential hang in pseudo ttys when generating ECHO output while the slave
is flooding the pty with output.

- Fix potential premature SIGHUP in pty code.
Addresses: https://cygwin.com/ml/cygwin/2015-03/msg00070.html

TIOCPKT mode of PTY is broken if ONLCR bit is cleared. * tty.h (class tty_min): Remove variable "write_error" to which any errors are not currently set at anywhere. (class tty): Add variable "column" for handling ONOCR. * tty.cc (tty::init): Add initialization code for variable "column". * fhandler.h (class fhandler_pty_master): Remove variable "need_nl" which is not necessary any more. "need_nl" was needed by OPOST process in fhandler_pty_master::process_slave_output(). (class fhandler_pty_common): Add function process_opost_output() for handling post processing for OPOST in write process. * fhandler_tty.cc (fhandler_pty_master::process_slave_output): Count TIOCPKT control byte into length to be read in TIOCPKT mode. Move post processing for OPOST to write process. Remove code related to variable "write_error". Return with EIO error if slave is already closed. (fhandler_pty_master::fhandler_pty_master): Remove initialization code for variable "need_nl". (fhandler_pty_common::process_opost_output): Add this function for handling of OPOST in write process. Add code to avoid blocking in non-blocking mode when output is suspended by ^S. (fhandler_pty_slave::write): Call fhandler_pty_common:: process_opost_output() instead of WriteFile(). Remove code related to variable "write_error". (fhandler_pty_master::doecho): Call fhandler_pty_common:: process_opost_output() instead of WriteFile(). * select.cc (peek_pipe): Remove code related to variable "need_nl".
