Motivation:
Implementation of WebSocketUtil/randomNumber is incorrect and might violate
the API returning values > maximum specified.
Modifications:
* WebSocketUtil/randomNumber is reimplemented, the idea of the solution described
in the comment in the code
* Implementation of WebSocketUtil/randomBytes changed to nextBytes method
* PlatformDependet.threadLocalRandom is used instead of Math.random to improve efficiency
* Added test cases to check random numbers generator
* To ensure corretness, we now assert that min < max when generating random number
Result:
WebSocketUtil/randomNumber always produces correct result.

Motivation:
I missed to reset the MessageDigest before reusing it. This bug was introduced by 79634e661b.
Modifications:
Call reset() on the MessageDigest.
Result:
Correctly reset MessageDigest before re-using
Motivation:
Creating a new MessageDigest every time is wasteful, we should store them in FastThreadLocal.
Modifications:
Change WebSocketUtil to store MD5 and SHA1 MessageDigest in FastThreadLocal and use these.
Result:
Less overhead and less GC.
- Add MessageBuf which replaces java.util.Queue
- Add ChannelBuf which is common type of ByteBuf and ChannelBuf
- ChannelBuffers was renamed to ByteBufs
- Add MessageBufs
- All these changes are going to replace ChannelBufferHolder.
- 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.
