48f2e705d9 Resurrect channel deregistration and constructor changes
Motivation:

Due to the complexity of handling deregistration and re-registration of
a channel, we previously decided to remove the deregister() operation
completely to simplify our code.  However, we realized that it shouldn't
be that complicated to implement it during our discussion about making
I/O scheduling more flexible and more customizable [1], and thus the
removal of deregistration and re-registration is unnecessary now.

Modification:

- Revert commit c149f4bcc0c0d02aa1abcd5e39c155a9e598822e
- Revert commit e743a27e752f0badaf71688457793d0aa365a3ac
- Make some additional adjustments

Result:

- deregister(), fireChannelUnregistered(), and channelRegistered() were
  added back..
- Channel constructors do not require an EventLoop anymore.

110745b0eb Remove the distinction of inbound handlers and outbound handlers
- Fixes #1808
- Move all methods in ChannelInboundHandler and ChannelOutboundHandler up to ChannelHandler
- Remove ChannelInboundHandler and ChannelOutboundHandler
- Deprecate ChannelInboundHandlerAdapter, ChannelOutboundHandlerAdapter, and ChannelDuplexHandler
- Replace CombinedChannelDuplexHandler with ChannelHandlerAppender
  because it's not possible to combine two handlers into one easily now
- Introduce 'Skip' annotation to pass events through efficiently
- Remove all references to the deprecated types and update Javadoc

132af3a485 Introduce ChannelHandlerInvoker, dedeciated for invoking event handler methods, and move most handler invocation code in ChannelHandlerContext to the default ChannelHandlerInvoker implementation
- Fixes #1912
- Add ChannelHandlerInvoker and its default implementation
- Add pipeline manipulation methods that accept ChannelHandlerInvoker
- Rename Channel(Inbound|Outbound)Invoker to
  Channel(Inbound|Outbound)Ops to avoid confusion
- Remove the Javadoc references to the package-private interfaces

129a2af86a Initial working version of the echo server example
- Optimized AbstractChannelBuffer.discardReadBytes()
- Split ChannelHandlerInvoker into ChannelInboundInvoker and
  ChannelOutboundInvoker
  - Channel implements ChannelOutboundInvoker
  - ChannelOutboundInvoker.nextOut() is now out()
  - ChannelOutboundHandlerContext.out() is now prevOut()
  - Added the outbound operations without future
    parameter to ChannelOutboundInvoker for user convenience
- All async operations which requires a ChannelFuture as a parameter
  now returns ChannelFuture for user convenience
- Added ChannelFutureFactory.newVoidFuture() to allow a user specify
  a dummy future that is of no use
  - I'm unsure if it is actually a good idea to introduce it. It might
    go away later.
- Made the contract of AbstractChannel.doXXX() much simpler and moved
  all common code up to AbstractChannel.DefaultUnsafe
- Added Channel.isOpen()
- Fixed a bug where MultithreadEventLoop always shut down its child
  event loops on construction
- Maybe more changes I don't remember :-)

368156f5d0 Another round of the new API design
- Channel now creates a ChannelPipeline by itself

  I find no reason to allow a user to use one's own pipeline
  implementation since I saw nobody does except for the cases where a
  user wants to add a user attribute to a channel, which is now covered
  by AttributeMap.

- Removed ChannelEvent and its subtypes because they are replaced by
  direct method invocation.
- Replaced ChannelSink with Channel.unsafe()
- Various getter renaming (e.g. Channel.getId() -> Channel.id())
- Added ChannelHandlerInvoker interface
- Implemented AbstractChannel and AbstractServerChannel
- Some other changes I don't remember
