Subject: use posix-pty, and forward SIGWINCH

I discovered the posix-pty library while looking for a way to forward
SIGWINCH to the slave pty. It's taken care of a lot of nasty pty
handling details, so let's use it!

Unfortunately, this broke control-d exiting debug-me, which used to work
great. I think that the problem is that readPty never returns B.empty,
even on control-d. Or perhaps, posix-pty is doing something to the pty
that prevents control-d getting through.

I kept all the withoutMode code; at least withoutMode EnableEcho
is still needed.
