- ChannelBuffer gives a perception that it's a buffer of a
channel, but channel's buffer is now a byte buffer or a message
buffer. Therefore letting it be as is is going to be confusing.
- In computing, 'stream' means both byte stream and message stream,
which is confusing.
- Also, we were already mixing stream and byte in some places and
it's better use the terms consistently.
(e.g. inboundByteBuffer & inbound stream)
- 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.
- 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
