faf8becf2e Make use of ByteBufProcessor for extract initial line and headers 
This gives some nice performance boost as readByte() is quite expensive because of the index / replay checks.

- Fixes #2014
- Add the tests that mix JDK ZLIB codec and JZlib codecs
- Fix a bug where JdkZlibEncoder does not encode the GZIP header when nothing was written to te channel
- Fix a bug where the encoders do not consider the overhead of the wrapper format when calculating the estimated compressed output size.
- Fix a bug where the decoders do not discard the received data after the compressed stream is finished

407f0a36f5 Simplify bundle generation / Add io.netty.versions.properties to all JARs 
- Fixes #2003 properly
- Instead of using 'bundle' packaging, use 'jar' packaging.  This is
  more robust because some strict build tools fail to retrieve the
  artifacts from a Maven repository unless their packaging is not 'jar'.
- All artifacts now contain META-INF/io.netty.version.properties, which
  provides the detailed information about the build and repository.
- Removed OSGi testsuite temporarily because it gives false errors
  during split package test and examination.
- Add io.netty.util.Version for easy retrieval of version information

cbd8817905 Remove MessageList from public API and change ChannelInbound/OutboundHandler accordingly 
I must admit MesageList was pain in the ass.  Instead of forcing a
handler always loop over the list of messages, this commit splits
messageReceived(ctx, list) into two event handlers:

- messageReceived(ctx, msg)
- mmessageReceivedLast(ctx)

When Netty reads one or more messages, messageReceived(ctx, msg) event
is triggered for each message.  Once the current read operation is
finished, messageReceivedLast() is triggered to tell the handler that
the last messageReceived() was the last message in the current batch.

Similarly, for outbound, write(ctx, list) has been split into two:

- write(ctx, msg)
- flush(ctx, promise)

Instead of writing a list of message with a promise, a user is now
supposed to call write(msg) multiple times and then call flush() to
actually flush the buffered messages.

Please note that write() doesn't have a promise with it.  You must call
flush() to get notified on completion. (or you can use writeAndFlush())

Other changes:

- Because MessageList is completely hidden, codec framework uses
  List<Object> instead of MessageList as an output parameter.

14158070bf Revamp the core API to reduce memory footprint and consumption 
The API changes made so far turned out to increase the memory footprint
and consumption while our intention was actually decreasing them.

Memory consumption issue:

When there are many connections which does not exchange data frequently,
the old Netty 4 API spent a lot more memory than 3 because it always
allocates per-handler buffer for each connection unless otherwise
explicitly stated by a user.  In a usual real world load, a client
doesn't always send requests without pausing, so the idea of having a
buffer whose life cycle if bound to the life cycle of a connection
didn't work as expected.

Memory footprint issue:

The old Netty 4 API decreased overall memory footprint by a great deal
in many cases.  It was mainly because the old Netty 4 API did not
allocate a new buffer and event object for each read.  Instead, it
created a new buffer for each handler in a pipeline.  This works pretty
well as long as the number of handlers in a pipeline is only a few.
However, for a highly modular application with many handlers which
handles connections which lasts for relatively short period, it actually
makes the memory footprint issue much worse.

Changes:

All in all, this is about retaining all the good changes we made in 4 so
far such as better thread model and going back to the way how we dealt
with message events in 3.

To fix the memory consumption/footprint issue mentioned above, we made a
hard decision to break the backward compatibility again with the
following changes:

- Remove MessageBuf
- Merge Buf into ByteBuf
- Merge ChannelInboundByte/MessageHandler and ChannelStateHandler into ChannelInboundHandler
  - Similar changes were made to the adapter classes
- Merge ChannelOutboundByte/MessageHandler and ChannelOperationHandler into ChannelOutboundHandler
  - Similar changes were made to the adapter classes
- Introduce MessageList which is similar to `MessageEvent` in Netty 3
- Replace inboundBufferUpdated(ctx) with messageReceived(ctx, MessageList)
- Replace flush(ctx, promise) with write(ctx, MessageList, promise)
- Remove ByteToByteEncoder/Decoder/Codec
  - Replaced by MessageToByteEncoder<ByteBuf>, ByteToMessageDecoder<ByteBuf>, and ByteMessageCodec<ByteBuf>
- Merge EmbeddedByteChannel and EmbeddedMessageChannel into EmbeddedChannel
- Add SimpleChannelInboundHandler which is sometimes more useful than
  ChannelInboundHandlerAdapter
- Bring back Channel.isWritable() from Netty 3
- Add ChannelInboundHandler.channelWritabilityChanges() event
- Add RecvByteBufAllocator configuration property
  - Similar to ReceiveBufferSizePredictor in Netty 3
  - Some existing configuration properties such as
    DatagramChannelConfig.receivePacketSize is gone now.
- Remove suspend/resumeIntermediaryDeallocation() in ByteBuf

This change would have been impossible without @normanmaurer's help. He
fixed, ported, and improved many parts of the changes.

7884574c7b Remove freeInboundBuffer() and freeOutboundBuffer() which has no value 
- Fixes #1308

freeInboundBuffer() and freeOutboundBuffer() were introduced in the early days of the new API when we did not have reference counting mechanism in the buffer. A user did not want Netty to free the handler buffers had to override these methods.

However, now that we have reference counting mechanism built into the buffer, a user who wants to retain the buffers beyond handler's life cycle can simply return the buffer whose reference count is greater than 1 in newInbound/OutboundBuffer().

af4b71a00e Remove special handling of Object[] in codec framework (a.k.a unfolding) 
- Fixes #1229
- Primarily written by @normanmaurer and revised by @trustin

This commit removes the notion of unfolding from the codec framework
completely.  Unfolding was introduced in Netty 3.x to work around the
shortcoming of the codec framework where encode() and decode() did not
allow generating multiple messages.

Such a shortcoming can be fixed by changing the signature of encode()
and decode() instead of introducing an obscure workaround like
unfolding.  Therefore, we changed the signature of them in 4.0.

The change is simple, but backward-incompatible.  encode() and decode()
do not return anything.  Instead, the codec framework will pass a
MessageBuf<Object> so encode() and decode() can add the generated
messages into the MessageBuf.

ff5aec0c78 Replace TypeParameterFinder with TypeParameterMatcher 
- We can avoid reflective matching using byte code generation.
 - Better matching performance when message type is Object

d4742bbe16 Clean up abstract ChannelHandler impls / Remove ChannelHandlerContext.hasNext*() 
- Rename ChannelHandlerAdapter to ChannelDuplexHandler
- Add ChannelHandlerAdapter that implements only ChannelHandler
- Rename CombinedChannelHandler to CombinedChannelDuplexHandler and
  improve runtime validation
- Remove ChannelInbound/OutboundHandlerAdapter which are not useful
- Make ChannelOutboundByteHandlerAdapter similar to
  ChannelInboundByteHandlerAdapter
- Make the tail and head handler of DefaultChannelPipeline accept both
  bytes and messages.  ChannelHandlerContext.hasNext*() were removed
  because they always return true now.
- Removed various unnecessary null checks.
- Correct method/field names:
  inboundBufferSuspended -> channelReadSuspended

bfe44180f9 Fix SnappyFramedDecoder issues 
- Checksum header was being incorrectly read due to incorrect order of
  shift and masking operations.
- Length field of 1-byte copy was being incorrectly interpreted due to a
  typo in the binary mask used to extract it.
- Use ByteBuf.readUnsignedByte() instead of readByte() & 0xff
- Use bitwise-OR wherever possible
- Use EmbeddedByteChannel to test
- Use ByteBuf comparison instead of array comparison
- Work done by @lw346 and then revised by @trustin
