Proof-of-concept encoder for parallel compression. Add a version of the brotli encoder that compresses each meta-block independently, only using the original input data from previous meta-blocks and nothing from the compressor state. This is a proof-of-concept to show that the current format is flexible enough to support parallel multi-threaded compression.
Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.
The specification of the Brotli Compressed Data Format is defined in the following internet draft: http://www.ietf.org/id/draft-alakuijala-brotli
