POLL_OUT in ttys, misc bug fix

Hi Marcelo!

Yes, I have been testing them with userspace applications (most notably User Mode Linux).

The following program's output gets truncated on a pty running on a normal kernel, but works fine when the patch is applied:
www.corewars.org/pollout.c

Also, the version I'd sent you earlier did not have a fix for serial.c, which exhibits the same problems. I've posted another version earlier today which includes this as well as a minor change to the second bug fix. Please use the new version instead of the earlier one.

Cheers,
Sapan
