Updates to Brotli compression format, decoder and encoder

This commit contains a batch of changes that were made to the Brotli compression algorithm in the last month. Most important changes: * Format change: don't push distances representing static dictionary words to the distance cache. * Fix decoder invalid memory access bug caused by building a non-complete Huffman tree. * Add a mode parameter to the encoder interface. * Use different hashers for text and font mode. * Add a heuristics to the hasher for skipping non-compressible data. * Exhaustive search of static dictionary during backward reference search.
