pty: Define 'struct winsize' on all platforms.

[Collin Funk]

Since termios.h defines 'struct winsize' on all platforms I think that
pty.h should also do the same. I've committed a patch doing that and
adding a basic C check program for types.

BTW, I think this fixes a very minor bug. Since the 'pty' module does
not directly depend on 'termios' but pty.in.h unconditionally includes
termios.h it would fail on Windows, for example. Very minor since I
think 'forkpty' and 'openpty' would import both header modules. Instead
of depending on only 'pty' directly.
