◆ set_socket_timeouts()

void set_socket_timeouts	(	int	fd,
		double	timeout
	)

Attempt to set socket-level timeouts.

These aren't supported by all platforms, and some platforms allow them to set but ignore them, so we can't easily report failure.

Also sets SO_KEEPALIVE (if supported), which should ensure a stuck connection will eventually time out, though it may take up to ~2 hours.
