catch SIGTSTP and save/restore terminal settings (#4460)
As far as I can tell, it is the responsibility of the program to save
and restore its own terminal settings across a suspend/foreground, the
shell doesn't do it (which seems odd).  So I've added a signal handler
for SIGTSTP to the RTS which will save and restore the terminal
settings iff we modified them with hSetBuffering or hSetEcho (we
already restore them at exit time in these cases).
