[Performance] Attempt to use Netty's Epoll implementation on Linux.

This will attempt to make use of Netty's EpollEventLoopGroup and Epoll(Server)SocketChannel when on Linux and the native libraries load correctly. It should bring a large increase in performance and hopefully reliability. Big thanks to the @netty team for implementing this and @normanmaurer for some tips on the support detection.

Feedback is appreciated.
Actually include native code, thanks again @normanmaurer
