1. kqueue: remove timeout from unix.Kevent() (#480) …

   The timeout for unix.Kevent() is causing issues; every 100ms it will do a new
   unix.Kevent() syscall, which isn't too efficient: even if you have just one
   change an hour, you will still keep calling kevent() ten times per second,
   resulting in a needlessly high CPU usage.
   
   Without a timeout, kevent() will block indefinitely until there are some events,
   which is much more efficient. We can't just remove the timout however, since we
   can't interrupt the kevent() call on FreeBSD and NetBSD, and it will hang
   forever. This issue is described in more detail here:
   fsnotify/fsnotify#262 (comment)
   
   To solve this we register a new kevent() with the file descriptor set to the
   closepipe; when this pipe is closed an event is sent and kevent() will stop
   blocking.
   
   This is a rebased version of #124.
