Switch Looper back to using poll() instead of epoll().

Added a couple of micro-optimizations to avoid calling wake() unnecessarily
and reduce JNI overhead slightly.

Fixed a minor issue where we were not clearing the "next" field of Messages
returned by the MessageQueue so the Message would hold on to its successor
and potentially prevent the GC from collecting it if the message were leaked
somehow.
