  Update (#749)
  
  Update:
  
   * Bazel: fix MSVC configuration
   * C: common: extended documentation and helpers around distance codes
   * C: common: enable BROTLI_DCHECK in "debug" builds
   * C: common: fix implicit trailing zero in `kPrefixSuffix`
   * C: dec: fix possible bit reader discharge for "large-window" mode
   * C: dec: simplify distance decoding via lookup table
   * C: dec: reuse decoder state members memory via union with lookup table
   * C: dec: add decoder state diagram
   * C: enc: clarify access to static dictionary
   * C: enc: improve static dictionary hash
   * C: enc: add "stream offset" parameter for parallel encoding
   * C: enc: reorganize hasher; now Q2-Q3 require exactly 256KiB
             to avoid global TCMalloc lock
   * C: enc: fix rare access to uninitialized data in ring-buffer
   * C: enc: reorganize logging / checks in `write_bits.h`
   * Java: dec: add "large-window" support
   * Java: dec: improve speed
   * Java: dec: debug and 32-bit mode are now activated via system properties
   * Java: dec: demystify some state variables (use better names)
   * Dictionary generator: add single input mode
   * Java: dec: modernize tests
   * Bazel: js: pick working commit for closure rules
