connect(2) in xconnect() by temporarily setting O_NONBLOCK on the socket and using xpoll() to wait for the operation to succeed. The timeout used is the '-q quittime' argument (defaults to 60s for accept(2), and the system default for connect(2)). Idea inspired by discussion with Chuck Cranor. This may (indirectly) fix various problems with timeouts in active mode through broken firewalls. Implement xpoll() as a wrapper around poll(2), to make it easier to replace on systems without a functional poll(2). Unconditionally use xpoll() instead of conditionally using select(2) or poll(2).
