Initial Redis Codec Implementation (#161)
Motivation: Added/Ported Redis codec support into DotNetty Modifications: - Added Redis Codec project - Added Redis Codec unit test project. - Extra: Added DefaultByteBufferHolder to DotNetty.Buffers. - Extra: Added UnrealeasableByteBuffer to DotNetty.Buffers. Result: Redis codec supported by DotNetty.
