[Bug general/3928] Pty.cxx frysk::sys::Pty::setUpPtyForConsole uses system() calls to set tty properties

What the system() stuff below is doing is setting the way the tty works.  It
could be done w/o system() by using terminal control ops similar to the following:

{
  struct termios tio;

  if (0 > tcgetattr(fd, *tio)) return -1;

  tio.c_lflag |= ICANON | ECHO;
  tio.c_cc[VMIN] = 1;

  if (0 < tcsetattr(fd, TCSANOW, ,&tio)) return -1;

  return 0;
}

where fd is the file descriptor associated with pts_name.

There are a few other wrinkles that might be relevant, but they'd depend on what
else is going on.
