Browse Source 
* fhandler.h: Define *_output_mutex macros for serializing tty output.
(fhandler_termios): Remove restart_output_event.  Define dummy output mutex
methods.
(fhandler_pty_master): Remove unneeded fixup_after_fork method.
* fhandler_termios.cc (fhandler_termios::line_edit): Acquire output_mutex when
CTRL-S is hit.  Release it on CTRL-Q.

inappropriate OutputStopped test here.  Just use the output mutex.

restart_output_event.
(fhandler_tty_common::close): Ditto.
