As the poll() manual says that events field may be specified as zero, in which case the only events that can be returned in revents are POLLHUP, POLLERR, and POLLNVAL. This patch allows luv to support this call method with events equal zero. When the parameters in the lua is an empty string, it means that events is zero.
