Fixed NPE in WebSocket00FrameDecoder if end couldn't be found in text frame

Motivation:
When we receive an incomplete WebSocketFrame we need to make sure to wait for more data. Because we not did this we could produce a NPE.

Modification:
Make sure we not try to add null into the RecyclableArrayList

Result:
no more NPE on incomplete frames.
Implemented LZF compression codec

Motivation:

LZF compression codec provides sending and receiving data encoded by very fast LZF algorithm.

Modifications:

- Added Compress-LZF library which implements LZF algorithm
- Implemented LzfEncoder which extends MessageToByteEncoder and provides compression of outgoing messages
- Added tests to verify the LzfEncoder and how it can compress data for the next uncompression using the original library
- Implemented LzfDecoder which extends ByteToMessageDecoder and provides uncompression of incoming messages
- Added tests to verify the LzfDecoder and how it can uncompress data after compression using the original library
- Added integration tests for LzfEncoder/Decoder

Result:

Full LZF compression codec which can compress/uncompress data using LZF algorithm.
Implemented a Bzip2Encoder

Motivation:

Bzip2Encoder provides sending data compressed in bzip2 format.

Modifications:

Added classes:
- Bzip2Encoder
- Bzip2BitWriter
- Bzip2BlockCompressor
- Bzip2DivSufSort
- Bzip2HuffmanAllocator
- Bzip2HuffmanStageEncoder
- Bzip2MTFAndRLE2StageEncoder
- Bzip2EncoderTest

Modified classes:
- Bzip2Constants (splited BLOCK_HEADER_MAGIC and END_OF_STREAM_MAGIC)
- Bzip2Decoder (use splited magic numbers)

Added integration tests for Bzip2Encoder/Decoder

Result:

Implemented new encoder which can compress outgoing data in bzip2 format.
