Include sys/termios.h for files which need it. * tty.h: New file. * shared_info.h: New file. * fhandler.h: Move inline methods that rely on tty stuff to fhandler_console.cc. * fhandler_tty.cc (fhandler_pty_master::process_slave_output): Set output_done_event immediately after reading data to speed up tty output processing. (process_output): Set write_error to errno or zero. (fhandler_tty_slave::write): Check previous write error prior to writing to slave end of pipe. This allows tty output to be slightly less synchronous. * fhandler_console.cc (fhandler_console::tcsetpgrp): Moved here from fhandler.h. (fhandler_console::set_input_state): Ditto.
