Brotli custom LZ77 dictionary support. Adds functions to prepend such dictionary to the encoder and decoder, and twiddles their internal parameters to do as if that was a previous part of the input. This dictionary is just a prefilled LZ77 window, it is not related to the built in transformable brotli dictionary.
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
