Relevant Changes

1. ServerBootstrap no longer takes a ServerSocketChannelFactory in its constructor. We used to use this to configure the thread pools. Looks like EventLoopGroup or its relatives are the place to look.

2. Same thing as #1 is true for ClientSocketChannelFactory.

3. ChannelPipelineFactory is gone. Looks like one uses .childHandler() with a ChannelInitializer instead.

4. What's up with ThreadRenamingRunnable in DefaultHttpProxyServer?

5. DefaultChannelGroup?

6. SimpleChannelUpstreamHandler -> SimpleChanneInboundHandler

7. InterestOps is gone - what does this mean to setReadable() and channelInterestChanged() ?

8. channelOpened() -> channelRegistered() ?

9. channelClosed() -> channelDeregistered() ?
