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
