50fafdc3d3 Rewrite SslHandler / Reduce the chance of OIO-OIO dead lock
- SslHandler always begins handshake unless startTls is true
  - Removed issueHandshake property
  - If a user wants to start handshake later, he/she has to add 
    SslHandler later.
- Removed enableRenegotiation property
  - JDK upgrade fixes the security vulnerability - no need to complicate
    our code
- Some property name changes
  - getSSLEngineInboundCloseFuture() -> sslCloseFuture() 
- Updated securechat example
- Added timeout for handshake and close_notify for better security
  - However, it's currently hard-coded.  Will make it a property later.

10f7a31908 Fixed SpdySessionHandlerTest / Fixed NPE in EmbeddedChannel
- Some tests like SpdySessionHandlerTest accesses outbound buffer
  even before the outbound buffer is initialized by
  AbstractEmbeddedChannel's subclasses, leading to NPE at <init>.
  To fix this problem, subclasses now pass the outbound buffer as
  a constructor parameter to AbstractEmbeddedChannel.

7bc10f2eba Replace codec embedder with EmbeddedChannel which can test any handlers
- Added EventExecutor.inEventLoop(Thread) and replaced executor identity
  comparison in DefaultChannelPipeline with it - more elegant IMO
- Removed the test classes that needs rewrite or is of no use

aab71ccd8a Remove Channel(Inbound|Outbound)HandlerAdapter which does nothing
- Thanks to the recent refactoring, Channel(Inbound|Outbound)Handler-
  Adapter ended up having empty body.  No need to keep.

ea0c9cfe79 Post-overhaul fixes / Split LoggingHandler into three
- LoggingHandler now only logs state and operations
- StreamLoggingHandler and MessageLoggingHandler log the buffer content
- Added ChannelOperationHandlerAdapter

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

0aa99606d9 Fix a race where 2 handlers in different threads access the same buffer
- DefaultChannelPipeline detects such cases and creates an object called
  'bridge' that works as a man-in-the-middle to deal with a race
  condition
- Slight performance drop is observed but still faster than v3. 
  Couldn't find much from a profiler yet.

f3734e1eb9 Simplified DefaultChannelPipeline by making its list head final
- Previously, head was a volatile field which is null at the beginning.
  While iterating over the pipeline, if the loop hits null, it called
  Channel.Unsafe explicitly.
- Instead, I created an outbound handler that redirects all requests
  to the unsafe and made it a final field of the pipeline.
- As a result, DefaultChannelPipeline code became much simpler.

3b2c25e8ed Rename (Server)Bootstrap.(child)initializer to (child)handler
- The handler you specify with initializer() is actually simply added
  to the pipeline and that's all.  It's ChannelInitializer which does
  additional work.  For example, a user can specify just a single
  handler with initializer() and it will still work.  This is especially
  common for Bootstrap, so I renamed initializer to handler, which makes
  more sense.

01a5bd41f0 Add Channel.type() which tells if stream-oriented or message-oriented
- DefaultChannelPipeline uses this information to reject invalid buffer
  access in inbound(Message|Byte)Buffer.  Otherwise, a user can access
  a message buffer when the channel is stream-oriented.
- Because ChannelType cannot be both STREAM and MESSAGE, catch-all
  buffer has been removed to avoid confusion and unexpected behavior
  (it's already causing headache.)
- As a result, codec embedder needs rework.

cc4f705029 Replace ChannelBuffer.toByteBuffer() with hasNioBuffer() and nioBuffer()
... just like we do with byte arrays.  toByteBuffer() and
toByteBuffers() had an indeterministic behavior and thus it could not
tell when the returned NIO buffer is shared or not.  nioBuffer() always
returns a view buffer of the Netty buffer.  The only case where
hasNioBuffer() returns false and nioBuffer() fails is the
CompositeChannelBuffer, which is not very commonly used and *slow*.
