5e93d206ff Overhaul - Split ChannelHandler & Merge ChannelHandlerContext
- Extracted some handler methods from ChannelInboundHandler into
  ChannelStateHandler
- Extracted some handler methods from ChannelOutboundHandler into
  ChannelOperationHandler
- Moved exceptionCaught and userEventTriggered are now in
  ChannelHandler
  
- Channel(Inbound|Outbound)HandlerContext is merged into
  ChannelHandlerContext
- ChannelHandlerContext adds direct access methods for inboud and
  outbound buffers
  - The use of ChannelBufferHolder is minimal now.
    - Before: inbound().byteBuffer()
    - After: inboundByteBuffer()
    - Simpler and better performance
    
- Bypass buffer types were removed because it just does not work at all
  with the thread model.
  - All handlers that uses a bypass buffer are broken.  Will fix soon.

- CombinedHandlerAdapter does not make sense anymore either because
  there are four handler interfaces to consider and often the two
  handlers will implement the same handler interface such as
  ChannelStateHandler.  Thinking of better ways to provide this feature

141a05c831 Strict thread model / Allow assign an executor to a handler
- Add EventExecutor and make EventLoop extend it
- Add SingleThreadEventExecutor and MultithreadEventExecutor
- Add EventExecutor's default implementation
- Fixed an API design problem where there is no way to get non-bypass
  buffer of desired type

7ddc93bed8 Ported IdleStateHandler / Forward-ported the UptimeClient example
- Add ChannelHandlerContext.eventLoop() for convenience
- Bootstrap and ServerBootstrap handles channel initialization failure
  better
- More strict checks for missing @Sharable annotation
  - A handler without @Sharable annotation cannot be added more than
    once now.

026715e818 Refactor the pipeline API to support stacked codecs
- Previous API did not support the pipeline which contains multiple
  MessageToStreamEncoders because there was no way to find the closest
  outbound byte buffer.  Now you always get the correct buffer even if
  the handler that provides the buffer is placed distantly.
  For example:
  
    Channel -> MsgAEncoder -> MsgBEncoder -> MsgCEncoder
  
  Msg(A|B|C)Encoder will all have access to the channel's outbound
  byte buffer.  Previously, it was simply impossible.

- Improved ChannelBufferHolder.toString()

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

cdd1ba93f0 Second round of new channel handler API design
- Rename ChannelReader to ChannelInboundHandler
- Rename ChannelWriter to ChannelOutboundHandler
- Introduce ChannelBufferHolder instead of adding the common super type
  of message buffers and byte buffers
  - This is more type-safe and natural.
- Remove the notification methods for buffer closure (might add back
  later when revisiting half-closed connection support)

22a815eaf8 Revamp channel handler API
- Merged LifeCycleAwareChannelHandler into ChannelHandler
- Replaced ChannelUpstreamHandler and ChannelDownstreamHandler with
  ChannelReader and ChannelWriter
  - These two new interfaces are much more type-safe than its ancestor.
- Simplified channel state model as described in #68
- Handler creates send/receive buffer.
  - Previously, Netty created them, but it led to more memory copies and
    inflexibility.  I'm going to allow a handler to create a bounded
    queue for example.
  - It currently uses Queue<T> but I'll define a new interface and make
    ChannelBuffer implement it (e.g. Queue<Byte>)
- Introduced AttributeMap which replaces attachments in Channel and
  ChannelHandlerContext and ChannelLocal

ebfc4513e0 Apply checkstyle to the build
Please note that the build will fail at the moment due to various checkstyle
violations which should be fixed soon

8663716d38 Issue #60: Make the project multi-module
Split the project into the following modules:
* common
* buffer
* codec
* codec-http
* transport
* transport-*
* handler
* example
* testsuite (integration tests that involve 2+ modules)
* all (does nothing yet, but will make it generate netty.jar)

This commit also fixes the compilation errors with transport-sctp on
non-Linux systems.  It will at least compile without complaints.
