Work around an epoll quirk where it sometimes reports just the EPOLLERR or EPOLLHUP event. In order to force the event loop to move forward, we merge in the read/write events that the watcher is interested in; uv__read() and uv__write() will then deal with the error or hangup in the usual fashion. Fixes #982.
