Instead of restoring the tty mode, restoring the signal handler,
unblocking the signal and redelivering it just make all our
signal handler interupt system calls and set a flag. We can just
deliver the signal at the end right before we would normally return.
This solves the SIG_IGN problem nicely and causes readpassphrase() to
return when someone hits ^C even if the handler is SIG_IGN.
